Ko-Teng has several close friends who had a crush on Shen Chia-Yi. Those friends of Ko's thus moved in unison from Ching Cheng’s junior high school straight into the senior high school division in pursuit of her.
Naughty in nature, Ko was ordered by their homeroom teacher to sit in front of honor student Shen for her to keep close tabs on him. The two hadn't hit it off at first but Ko gradually fell for Shen, who was always pressuring him to study hard. On the other hand, Shen became impressed by the contrasting values Ko represented. Ko started pursuing Shen but Shen remained hesitant.
After graduation from senior high, Ko and Shen almost became a couple but the deal was spoilt by a dukeout competition organized by Ko. (official website)
