Hello, I'm looking for a manga that I read long time ago. It's about two guys looking at a pornographic picture, and they think that she looks like a classmate the MC likes. Then two girls saw it and took it, and the four of them went home together and, well, 'banged'. They are high schooler i think no isekai or another world. Oh and there’s a scene when mc ask the girl why did she let him do with her, she said because he’s look like he want to do it

P.S. mc is kinda disappointing like he likes the girl but not have enough courage or smth.

I think it's Karami Zakari:

• Karami Zakari: Boku no Honto to Kimi no Uso (seinen) - you are probably looking for this one,
• Karami Zakari (hentai) - well, this is original manga.

Finally, thank you so much sir. you are the best!
