for his crush towards dohwi it's just a simple crush like teenager fall in love. all his life, sooyeon was never fully being loved by another person so when someone gave him smile and soft stares to him, they're enough reason to fall in love. remember when they met first time? dohwi smiled ears to ears when he saw sooyeon ((maybe because he's kind)) but actually dohwi was staring at something like black smoke surrounding sooyeon

i still don't get why and how sooyeon died and why did he have a crush on dohwi lol
