First of all,i'm sorry for my bad english ;-; So i'm looking for a manga where the main female lead is underestimated or overshadowed by her friends and people hardly notice her. I don't want her to be those weak annoying dumb female leads.Basically i want a manga where once people get to know the female lead she's not what they really thought she was.Much like the protagonist from OUJI-SAMA GAME (KIRISHIMA RIRA) Manga. I also really liked the female lead of cheese in the trap and would love if the female lead's thinking process is similar to hers.
No yaoi/shounen ai/shounen pls. Romance is optional but i would like it more if there's some into it 😀

Sukkite ii na yo, maybe?

Horimiya - Horimiya just happened to be published in a shounen magazine (it would easily fit in a shoujo magazine). I thought it was a shoujo until I looked at the genres. The female lead is relatable and not idealized. I think this manga fits your description really well. It is a romance.

Otomen - The heroine is different than people think she is. So is the male lead. But I wouldn't really call them overshadowed. The guy is the main character in this shoujo.

Koi da no ai da no - Maybe. People tend to underestimate the heroine.

I've read sukkite ii na yo before, not exactly what i'm looking for

@meredithbecca
I've read otomen and koi dan no ai da no ( one of me favs) 😀 although i haven't read horimiya yet, i put that aside before thinking it might be one of those cliche romances, will try that now! Thanks.
