He's your classmate and best friend, although neither of you will ever admit it. You both love spending time together, even if it just involves sitting next to each other in complete silence. You spend so much time together that it could be say that he lives with you. He feel soo good in your company. You're like Sae to him before he went to Spain. Even like now, when you watch a horror movie together, he rests his head on your shoulder to feel that you are close while he is focused on movie.
