Hello Neighbor

College student Shin Ryujin has recently moved due to family stuff, and was currently living with her parents and her sister, Yuna.

There she meets her new neighbors, the Hwangs. She becomes good friends with Hwang Hyunjin, and gains a crush in his little sister, Hwang Yeji.

A few years later, Yeji and Ryujin reunite on a blind date set up by Ryujin's friend, Lia. It turns out Yeji had returned from a vacation, and was also moving in with Ryujin.
