I will live as a supporting role in this life

Low-Self-Esteem, the Manga.

Girl is a reincarnator with trauma that gets born into a noble family with a trash father who gives her trauma. She wants to try to not stand out for some reason, thinking that her life will be easier if she barely squeaks by. She never considers the obvious choice of “Find rich husband” because reasons.

She is humble and shy and beautiful without knowing she is beautiful. She is holding back but accidentally does amazing which gives her friends inferiority complexes. She thinks everyone at home hates her, but SURPRISE, everyone LOVES her, except her shit dad who caused her trauma. She gets cookies.

She meets a badboy who is bad because trauma.
She does not want to get noticed, so she gets noticed.
She is not like other girls and is the only one who understands.
There is the bad boy, the good boy, and the lazy boy. They all bring her warm clothing to wear when the snow comes because f’in symbolism.
Her friends are all bundles of trauma.
There is accidental hand holding, cock blocking, FL so dense she curves light around her, and lips that accidentally get so close you think they are gonna kiss but don’t and FL blushes, but does know why she blushes because they are just friends, But oddly enough, I have yet to see a single wall slam or princess carry.

To prove she is not a mary sue, she cannot cook worth a damn. THERE. SHE HAS A FLAW. EVERYONE LOVES HER BUT SHE CAN’T COOK. NOT A MARY SUE. I REPEAT. NO MARY SUES HERE.
