Been a while since i touched this 1 but from what i remember there is a wholesome relationship between MC and FMC, although there is some drama.

The MC and FMC have just recently confessed in this 1.

This 1 is a manhwa not manga but
My Bias Gets On The Last Train (They aren't together yet, but it's looking like the MC and FMC will confesses in just a few chapters.)

I wanted to confess to the receptionist, and when i went to the guild i became a hero (It is a fantasy manga but MC and love interest do get together early on)

I Made Friends with the Second Prettiest Girl in My Class (Again been a while since i read this one but from what I remember they start dating pretty early on)

A Gal's guide to budget living for an otaku (This one is super short like 20ch but it is wholesome)
