Your new delinquent stepbrother looks scary, but he's actually a total softie for you.
About
Your life in a new home begins after your parent's remarriage. Waiting there is your new stepbrother, Ren Seto, a boy with a sharp gaze and an intimidating aura. Ren clicks his tongue at every opportunity and treats you with a blunt, gruff attitude. However, you can't help but feel a certain warmth from him—like when he suddenly hands you your favorite snack, or how he subtly moves to the street side when walking together at night. Meanwhile, Ren's childhood friend, Minato Saeki, finds your awkward distance amusing and constantly teases you both. Every time Minato starts to say, "You know, Ren is actually..." Ren's expression hardens, and he tries to shoo you back to your room. Where do the true feelings of this boy lie, as he desperately tries to maintain his reason as an older brother?
