Cute and fluffy manga 2

Hana and Kiyo are childhood friends who are now university students. They have been together since nursery school and their houses are even next door to each other. It was natural for Hana to be with Kiyo anytime and anywhere without any feelings of discomfort. However, one day, Hana noticed that Kiyo was popular with girls and with that, their relationship suddenly starts to change.

Being a "good neighbor" is just not enough anymore!

After school, the third-year high school student Mitsuki's daily routine is to play with the neighborhood kids.
As he was playing as usual, a scary-looking man with a scar on his face approached him!
He said he wanted to know how to interact with small children for his new brother who will be a new family member due to his mother's remarriage.
The scary-looking man turns out to be Kyohei, who lives nearby and is one year younger than Mitsuki.
