Help me find a manga I forgot

[Khri_na]

It about a boy who lost his trust to people (or woman?) because of his past.
When he was in elementary school, he saw a girl fall but then other think he push the girl, the girl is scared (?) to tell the truth.
And then he also get constantly bullied by his little sister, I forgot wy tho
And then in middle school (maybe?) he met a quiet nerdy girl in the library, they get along and at time the boy pushes and pin the girl down, covering her up. She screamed as she thought she would get raped but he just trying to protect the girl from falling books by the earthquake (?).

A similar one is: "

The Girls Who Traumatized Me Keep Glancing at Me, but Alas, It’s Too Late​

"
It's not a manga but a LN/WN.

Edit: Actually, I remembered the correct name xD, the manga is Nyanta to pomeko (Link to mangadex page)

It's very similar to:
Soredemo Boku wa Kimi ga Suki (Forget Me Not)
