need help finding doujinshi title! [NSFW]

it's a story about this shy schoolgirl having a crush on this big, beefy guy who helped her with guys who was trying to hit on her (threw a soda can at them?), then i think he invites her over to his house, both of them confess their crushes to each other, then they have sex. it's a really cute doujin but the sex is really hot lol

thanks !
