I read this manga online about six years ago it has a light blue cover with nothing outside, maybe just the name.
The story revolves around three childhood friends who live in a small town where just the three of them study together, they frequently start to frequent each other's houses and discover their first sexual experiences qnd love between them, the manga must have been released around the 2000's because of the appearance of the characters that look like they were from an older manga.
it's not an extremely explicit manga that I could call hentai nor something ecchi just some lolicon
I would like help finding his name, thank you 🙂
