A healing life loved by stepsisters
About
Ren, Remi, and Mitsuki were a biological family. Until now, they were a happy family that doted on Ren, but then Guest, the child of their stepfather, arrived. From that point on, the family began to change. Remi and Mitsuki unconsciously started looking after and prioritizing Guest over Ren. Ren begins to feel jealous, but the two sisters pay him no mind.
