Shocking! This student is phenomenal!

A story of a school beauty, a top student, a super-rich man, a national hero, an entertainer, and a single female lead who are mutually devoted to each other.
Also known as "Shocking! This student is too prodigy!", "Late at the start, I shocked everyone by reciting the text backwards!", and "Just started military training, the school beauty personally helped me bribe the drill instructor!"
(The male and female leads meet relatively late; the first 40 chapters will hold them together, while their university life, including military training, will begin after their first meeting around chapter 80.)
Because of the vast difference in their circumstances, Su Jiang, who was childhood sweetheart, suddenly received a system.

After meeting:
"Little Su Su, this is a three-piece facial cleanser set I brought back for you from abroad. This is for washing, this is for toner, and this is for lotion. You should wash your face first, then apply the toner, and finally apply the lotion."
"Little Su Su, this toothpaste is really good. I bought it for you from abroad. It's said that it won't cause mouth ulcers. You used to get mouth ulcers a lot when you were little."
"Little Su Su, here's another one. These are three towels: one for washing your face, one for washing your body, and one for drying your feet. Don't use one towel for both your head and the bottom."
"Little Su Su..."
The rest of the group: Holy crap, Su Jiang is a pervert, and you guys are showing off your love too!
(This isn't a purely wish-fulfillment story; it contains some social realities. Some readers might find it a little angsty in the beginning, but it gets better later on.)
