Help me recollect

I can't remember the title, maybe someone could help, I only remember it was school life and rather slice of life, yaoi, very nice art, and I remember the two studying in one's house and it was very hot outside (the weather was hot in general), there was a festival , and one MC vas rather forcing the other to meet with a girl, because he thought the ther was interested. And there was a scene at the rooftop during fireworks (they always watched them together) and MC was standing alone thinking the other was watching them with a girl, and then his crush rushed through the door and everythinh was clear. I know it's common but it was really nice manga...
