–Formally introduced in chapter 37-
Lu Xuan Run
Even though he is not from the main couple I loved his introduction into the story and how ambitious he is towards Kang Jinha.
Hell, he is way hotter and smarter than Siwon, and obviously desires Kang Jinha more. It made me root for him to end up together with Kang Jinha.

I´m sorry to those who didn´t get to read this story as it was coming out cuz I´m reveling the big plot twist by putting this manga in this list, but I just loved this story so much.

Kanao (uke) is a popular student that befriends Sei at highschool and even become roomates. He´s revelead to be a yandere that orquestrated a whole plan for Sei to confess he loved Kanao.
