I thought I hated you (leehan + Riwoo)

Riwoo and leehan have been Enemies since birth. So their dad's were business Enemies. And since then they always say false rumors about each other. Riwoo doesn't believe his dad since he saw how kind Leehan's father is to his small business customers . But in that other hand. Is the most stubborn man alive. Wait no most stubborn PERSON alive. It's Leehan. He doesn't believe any word his dad says. He loves his father so he stays away from riwoo as much as possible. His dad had cancer. He has 3 years left. Yes..it is really hard for him. But he will do everything his dad wants him to. And the first thing is to be Enemies with riwoo. The truth is. He love Riwoo. Will love is a strong word. Let's say likes Riwoo. It is really hard for leehan. But he tried his best to not grow any relationships with him. Sungho and Taesan have been having a crush on each other since tenth grade. Now they are in 12 grade and they are still the same crushing over each other. My lovebirds . Woonhak has a crush on his senior and that is Jaehyun. They like each other but they don't know it.
