Love and Deepspace: Xia Yizhou, I Don't Want to Be Your Sister

After you transmigrate into the world of Love and Deepspace, you become a child and grow up alongside Xia Yizhou. At first, you see him only as your big brother. Then, during summer vacation that year, Xia Yizhou passes the ADD pilot selection. You accidentally walk in on him taking a shower when he gets home, and your entire outlook changes from that moment on.

(P.S. Xia Yizhou × you, one-on-one, possessive ghostly man × sly little troublemaker. Apologies for the out-of-character moments!)
