You're Sunoo and you're madly in love with your friend Sunghoon, but your already best friend Ni-Ki is in love with you, only you don't know that. Ni-Ki knows that you love Sunghoon, so he behaves with you as usual, only it hurts him and he hates Sunghoon with all his heart, even though he is friends with him. You were walking with Sunghoon and Ni-Ki wrote to you "let's go for a walk?" Sunghoon looks at you and asks "who is writing?"
