Hi, sorry for bothering you.

I forgot the name of this romance manga I read a couple years ago about two high schoolers that started dating.

The story is set in a normal setting. So there's no sc-fi, magic, etc.

If I'm not mistaken, the girl has long black hair and always acts distant which makes her appear rude.(tsundere I guess).
I vaguely remember how the leads would have two best friends being in the classroom with them.

I already searched extensively throughout 10 search pages and I can definitely say it's none of the following manga:
Koisuru Yankee Girl
Yahari Ore no Seishun Rabukome wa Machigatte Iru.

Thanks in advance.

Would you say the lead female is confidant? Cause there's a tag for that.

The better you describe the leads the better to narrow it down.

Maybe Kyou no Yuiko-san

My current top 3:
Fullmetal Alchemist
Pandora Hearts
3-gatsu no Lion

Yes. Yes. Yes.

Thank you. You're the best.
I was afraid my description was all over the place but you did it.

You're awesome.
