Help me find a bl plz >,<

Does anyone know the bl story of a school boy who thinks he's in love with the new transfer student. When the story starts the transfer student really isnt sociable, but when the mc starts to know him better he starts crushing on him silently. All I remeber is the cover had two school boys sitting on the roof of the school. I think I also left off at the moment when the transfer student was going to allow the mc test out if he was really in love with him.
