My girlfriend is actually myself.

With some time before school started, Shiraishi Saku and Yukimiya Natsume returned to their bedroom, where Shiraishi Saku put the menstrual bag into the girl's schoolbag.

He zipped up his backpack and began to think about his period.

Although it's far from needing painkillers, there is still some discomfort during this period. Lower back pain and fatigue are secondary; what's most awkward is the feeling that I never thought I would experience in my life.

Just like at the beginning, his chest always felt heavy, and it took him a long time to get used to it.

Shiraishi Saku decisively switched from first-person perspective to God's-eye view, and sure enough, the strange feeling became much less intense.

Let's just maintain a God's-eye view these days.

He turned around and looked at the girl's body.

The girl lay motionless on the blanket, her long golden hair hanging down over her white school uniform shirt, her eyes tightly closed.

"uncomfortable"

Such thoughts came to the girl's brain.

"Get up and go to school." Shiraishi Saku patted her bottom.

"I don't want to move."

Not only did I not want to move, I didn't even want to speak; I could only communicate with my thoughts.

Fortunately, commands can still be sent from God's perspective.

Shiraishi Saku gave the order to get up, and the girl stood up as expected. He nodded, turned around to pick up his schoolbag, and when he turned back, the girl had already crawled back onto the blanket.

"...Get up and go downstairs," Shiraishi Saku sent the command again.

The girl swayed as she got up and went downstairs. Shiraishi Shuo, carrying two schoolbags, followed behind her, watching her go down the stairs and lie down on the sofa. There were no soft blankets on the sofa, so she had no choice but to lie down.

Shiraishi Saku fell silent. It felt like playing a simulation game and encountering those unreasonable characters; the moment the mouse left her, they started to give up.

This Yukimiya Natsune is a complete lazybones.

However, considering she's not even a month old yet, it's already quite impressive that she doesn't cry or fuss.

Abandoning the foster care model, Shiraishi Saku intervened again, and the lazy girl immediately perked up, took her schoolbag from Shiraishi Saku's hand, and walked out of the house.

"Hurry up," Sakura Nene urged. "Forget about Yukimiya-neechan, brother, why do you look so serious and walk so slowly? Did you come for your period too?"

I actually came!

The effect of this feeling was greater than he had expected, especially when walking. He took the girl's backpack to lighten her load, but the girl still continued to feel tired.

I feel like I've been given a persistent debuff.

He looked at his sister, who was still running and jumping around, and would greet familiar neighbors with a smile, even though she was at the same age.

He thought of how the girl had drunk iced milk so heartily the night before, and a feeling of envy welled up in his heart.

Is this the energy of a junior high school student? An old high school girl like me can't compare!

No, it's probably because the girl's physical condition is too poor.

The night she dressed up as a ghost, the zombie girl was so exhausted that she couldn't even eat her sister's brains.

This route to school, which usually makes the girl's body and legs ache, became an even greater test today.

Perhaps he should put training on his agenda.

After parting ways with his younger sister at the crossroads between the high school and junior high sections, Shiraishi Saku glanced at the tower behind him. If he lived here, he wouldn't have to walk so far.

However, that proud mother probably wouldn't allow her daughter to bring a man home.

"Yukimiya-chan, Shiraishi-kun!" A familiar voice rang out from below the tower.

Airi Asakura jogged over and joined the two of them.

Today, the prettiest girl in the class has an even more exquisite makeup look. She can't go without makeup; her dark circles are just too obvious.

Airi Asakura didn't sleep all night. Instead of taking the closer alley in front of the tower, she lay in ambush behind the tower, waiting for Shiraishi to run into her on his way to school.

She felt that her guess last night might not be accurate. Yukimiya-chan's failure to return to the tower didn't necessarily mean she stayed overnight at Shiraishi-kun's house; she might have gone to another residence.

This is easy to confirm; just check if Yukimiya-chan and Shiraishi-kun come to school together.

The truth filled her with sorrow and melancholy, but also a sense of relief. Yukimiya and Shiraishi had indeed come together, and they had indeed spent the night together; she truly had no hope.

Composing herself, she stepped out of her ambush position and met the two men.

She likes Shiraishi-kun, she admires Yukimiya-chan, and the person she likes is with the person she admires, so she should be even happier.

Smiling, Asakura Airi took Yukimiya Natsune's arm and turned to look at Shiraishi Saku, her gaze sweeping over the two schoolbags on the boy's shoulders.

She squinted and said, "How considerate, Shiraishi-kun."

In Japan, carrying a girlfriend's bag is not a common practice, and many women even refuse this gesture. Bags are something they buy to accessorize themselves, an integral part of their outfits; giving it to their boyfriends would mean they're missing an accessory. What's the point of carefully selecting a bag before going out?

"Xia Yin isn't feeling well," Shiraishi Saku responded.

This was the first time for both of them. Although he had done some research, he still thought it would be better to ask Asakura Airi for some guidance. If she had any tips on how to relieve the symptoms, that would be great!

When it comes to women's discomfort, the first thing that should come to mind is menstruation, but at this moment, Airi Asakura's mind was completely focused on "overnight stays," which inevitably led to a misunderstanding.

A logical equation popped into Airi Asakura's mind.

[After staying overnight] + [Feeling unwell] = [???]

"Ugh!" Airi Asakura stepped back in shock, staring at Saku Shiraishi in disbelief.

Although she had already guessed it, could she really just tell her this directly?

She was touched by this trust, but the whole thing was just too shocking for her!

She has never even held a boy's hand!

"What's wrong?" Shiraishi Saku asked.

"It's nothing," Airi Asakura waved her hand. "I was just overreacting."

She thought that this composure might be the mark of a mature person, and she should learn from Shiraishi-kun.

According to social etiquette, at this time, she should kindly ask Yukimiya-chan where she is feeling unwell and offer any help she can.

She took Yukimiya Natsune's arm again and politely asked, "Yukimiya-chan, are you feeling unwell?"

"My lower back is so sore, I have no strength," said Yukimiya Natsune.

They actually answered!

Airi Asakura was deeply shocked. If it were her, she would never have been able to ask, because asking is a form of confession, which is equivalent to telling the other person how that night had affected her body.

By the way, do you experience lower back pain and fatigue?

Airi Asakura, drawing on her limited knowledge, tried her best to reconstruct the "onset process" through the symptoms.

The fatigue is easy to explain; the R18 she was watching had this description: reaching the peak always consumes energy.

But what causes lower back pain? Shouldn't it usually be the man who experiences lower back pain?

Airi Asakura glanced at Saku Shiraishi's waist. The boy's waist was straight, and he didn't seem to be in any discomfort. Why was it Yukimiya-chan's waist that was sore?

In general, the man's back pain is because he is the one exerting force; Yukimiya-chan's back pain...

Airi Asakura covered her lips, her surprised eyes filled with reverence. It's Yukimiya-chan!

I've already told her about this position, is it really okay?

And why are you all looking at me with such eager expressions?! What are you expecting?!

I don't understand anything!

"Um..." Airi Asakura timidly raised her hand, "You don't think Yukimiya-chan and Shiraishi-kun think I'm experienced, do you?"
