Li Wei, a good student of Yang'an Middle School, moved from the first place in the next grade to the second place in the next grade after Gu Chu transferred to Yang'an, and was pulled away by Gu Chu. After this failure, Li Wei was very dissatisfied, so he observed Gu Chu's movements every day, and was bound to find out where he could surpass himself. However, during his daily observations and occasional conversations, he accidentally fell in love with Gu Chu, and began a long crush and pursuit. It's a pity that Gu Chu never liked her and treated her coldly until college...
When the two finally achieved success, Gu Chu suddenly remembered what Li Wei had vowed one summer,
"Gu Chu, if one day you really want to fall in love, remember to put me first, because you have to believe that no one can give you more happiness than me."
Hmm... Now that I think about it, it seems to make sense.
