Jiha x Inho
Jiha has known Inho since he was a baby, a baby with tiger-like qualities. They were good friends and made a pinkie promise to live together and get married, which Jiha forgot about until Inho showed up on his doorstep, about to start college and ready to live with him. Inho's had a crush on Jiha all along but Jiha is wildly oblivious.
