Neet to find this BL

So basically its about a black haired guy and a blonde one and if im not mistaken the blonde one has a mole on his face(maybe not). But they basically become friends to benefits and there is this one scene basically and the end where the blonde hair guy was in the hospital, on the roof top and the black haired guy was looking for him, and when he did find him they did the deed in the stairway. Um thats like what i remember(i dont even know if its correct) and i cant find it anywhere so if someone can help me, thank you!!! ╥﹏╥
