Only remember this clear detail: MC-kun worked in a cafe with tsundere-chan. They actually both play an online game and she eventually finds out that he is her friend in the online game.

I think he is an aspiring writer or manga artist or something similar and so he quits the cafe job when he has progress with that. His uncle might be a game programmer? He may also have a brocon sister.

I'm also looking for another light novel where MC-kun helps ice princess write a better light novel. He's basically a paid light novel reviewer,

and he helps ice princess with her relationship with her grandma

The second light novel is Manuscript Screening Boy and Manuscript Submitting Girl (Novel)
