The Angel Next Door Spoils Me Rotten (WN) (Volume 5+)

Continuation from Anime.

After a long, unrequited love, Amane and Mahiru took a step forward into a new relationship. They closed the distance bit by bit, baffled by each other's inexperience.

At school, the two of them were a hot topic of conversation, and Amane quickly grew tired of the commotion, but as he started to face his classmates, the way they viewed him also began to change. Mahiru, seeing the situation, seemed to grow uneasy...

Then summer vacation arrived! The two of them headed for the pool, and then went home to Amane's parents' house together. This was the path of their memories, which would only continue to accumulate!

This is a sweet, yet tantalizing love story with a cute neighbor!
