Boyfriend's passive-aggressive behavior, she turns the tables and makes him her backup option.

At the time, she had some doubts, but no concrete evidence.

Then, Lin Ziheng accidentally ate a mango cake but did not have an allergic reaction.

The fact that Lin Ziheng was rushed to the hospital long after the allergy period should have passed was unexpected.

At that time, Si Nian began to suspect that someone was playing tricks on Lin Ziheng because of his constitution.

However, she was too busy at the time and didn't have much time to focus on Lin Ziheng.

Now Lin Tinghan has told her personally that Lin Ziheng and she are not related by blood.

This made Si Nian want to find out more.

She helped Lin Tinghan sit back on the sofa and asked him, "Why did you suddenly say that? Didn't you two do a paternity test before?"

"The previous test results were tampered with. I went to Hengheng for a retest today, and I watched it with my own eyes. The report actually said that we are not related by blood."

Lin Tinghan sat on the sofa, his hands supporting his head. He lowered his head and said in a muffled voice, "Niannian, I don't know where things went wrong, why things turned out like this. If this part went wrong, then the whole plan is ruined."

Si Nian had heard from Lin Tinghan that everything he had planned for Lin Ziheng, and his plans, were closely related to every step Lin Ziheng took.

Now that he's being told that Lin Ziheng isn't his biological son, all his efforts have been in vain.

It's understandable that it's hard to accept at first.

Si Nian sat to the side, watching Lin Tinghan on the verge of collapse.

She moved her lips, but found herself unable to say anything comforting to Lin Tinghan.

Finally, all she said was, "You need to take care of yourself and not get too emotional."

Lin Tinghan looked up. "Niannian, do you think I'm ridiculous? I've been forced to choose between you and Hengheng all this time, and this is the result in the end."

"..."

"Niannian, why won't you answer me? Are you afraid my heart can't take it? Do you still worry about me now? Is your worry because of me as a person, or because of the beating heart in my chest?"

"I know you're upset, but I'm not the one who caused all of this. You shouldn't be here saying these things to me."

Lin Tinghan looked at Si Nian with mixed emotions.

He suddenly seemed to realize something, reached out and grabbed Si Nian, holding her shoulders, and said to her, "Niannian, I can't feel any concern from you. Is it because you still resent me? I didn't cheat on you, and Hengheng isn't my son..."

"If there really was no infidelity, then the excuse Hengheng gave when she appeared would not be believed by a normal person."

"But I really didn't! I believed it because... because..."

Lin Tinghan had the words on the tip of his tongue when he closed his eyes with difficulty and a pained expression.

"Before my heart transplant, I didn't know if I would survive the surgery, so I took my sperm and organelles and cultured them with Chen Bitong's... I thought that even if my surgery failed, I could leave something behind in this world."

Si Nian didn't quite understand, so she asked, "Did you do IVF back then?"

"You can understand it that way. But I have a serious heart condition that my offspring will definitely inherit, so in addition to in vitro fertilization, we added bionic technology to re-edit my genes and remove the heritable factors."

Si Nian suddenly realized, but what came to her mind was that one day after their wedding, Lin Tinghan excitedly told her that Hengheng had not inherited any of his illnesses.

"Niannian, so I really didn't cheat on you. Even though this child is related to me by blood, I still didn't cheat on you."

"..."

Si Nian still reached out and pushed Lin Tinghan away.

She moved back a seat, distancing herself from Lin Tinghan on the sofa. What she cared about now was no longer whether Lin Tinghan had cheated on her with Chen Bitong.

Over this period of time, Lin Tinghan's actions have long since eroded all the friendship between them.

When a person has no hope for a relationship, it means that they no longer have any feelings for it.

Lin Tinghan sighed heavily.

He leaned back on the sofa, staring at the ceiling, seemingly lost in thought.

He was certain that Lin Ziheng's existence was deliberately arranged by someone.

So who is this person?

Lin Ziheng misled him, creating an irreparable rift between him and Si Nian, and making his collaboration with Lairui Technology on the bionics project even more difficult.

When a name came to mind, Lin Tinghan's eyes flashed with murderous intent.

Lin Tinghan turned his head and looked at Si Nian with an ambiguous expression.

Just as he was making Si Nian feel uncomfortable, he suddenly stood up and left Yun Jin Mansion.

Si Nian frowned, hesitated for a moment, and then made a phone call to Lin Tinghan's mother, Zhao Yulan.

After the call connected, Si Nian hadn't even had a chance to speak.

Zhao Yulan then said sarcastically, "How come you still have time to call me? Haven't you gone on a date with your new boyfriend? You haven't even received your divorce certificate yet, and you've already found a boyfriend. You're really fast."

Si Nian knew that Zhao Yulan must have heard about the rumors that had been spread by the media about her and Xie Jingyao on the day of the press conference.

Si Nian didn't explain further and went straight to the point: "Aunt Lan, Lin Tinghan's mood is a bit off. You'd better have someone keep an eye on him."

Zhao Yulan paused for a moment, "What's wrong with him? Did you upset him again?"

"It has nothing to do with me; it's probably just some work-related troubles."

Si Nian did not tell Zhao Yulan that Lin Ziheng and Lin Tinghan were not related by blood.

She felt that if anyone should say it, it should be Lin Tinghan herself.

"I'll call him and tell him to come home."

"Oh, right, Aunt Lan, you said you'd process our divorce certificate by the end of the month, and today is the 30th."

Zhao Yulan paused slightly, then raised her voice a few decibels again, "What's the rush? Is it really necessary to get the divorce certificate so quickly and be with other men? Si Nian, after all these years, Ting Han has treated you quite well, hasn't he? How can you be so heartless?"

She had always worried that Si Nian would disagree with the divorce because she was unwilling to accept it and couldn't let go of Lin Tinghan.

Unexpectedly, when it came to actually getting them a divorce, it was their own son who vehemently disagreed!

Si Nian not only failed to salvage the relationship, but even found a new partner.

"Aunt Lan, I know you're talking to me like this because you've heard about my recent scandal. But Lin Tinghan knows the truth better than I do. If you're curious, you can ask him."

As for the divorce certificate, it was something we discussed a long time ago. It's not that we're rushing you to get it quickly so we can be with another man.

Si Nian added, "If you want Lin Tinghan and I to divorce, please get the divorce certificate processed as soon as possible."

Zhao Yulan never expected that Si Nian would cheat on her husband and be so self-righteous!

"I'll have someone deliver your divorce certificate to you right now!"
