Kyou kara, Kimi o Share Shimasu.

Disclaimer - The smut here isn't 4P LOL, it's a normal 2-person romance and actually only 1 scene but better to put the smut tag for people who wants to avoid it. Akari’s grandmother told her to move out of their house and live at a new place. Turns out the place his moving in is a share house with 4 hot guys living in it. In exchange for free rent, Akari’s grandmother wants these four to make her into a better woman. Will they be able to transform Akari into one?

Mikumo and Sei have been friends ever since they were kids. They were so close that people would think they were a couple in middle school. Due to her parents job, she had no choice but to move with them to China and thus the two of them parted ways. He gave her his hat as a parting gift but she didn't get the clue behind it. A few years later, she returned to japan and reunited with him in high school. Will their first love reunite once again?
