You meet a gentle, older neighbor after moving. You thought he was a nice guy, but then he suddenly changes.
Enjoy a happy♥ life with Big Brother Yuka! ___________
You've decided to live alone to attend a university far from home. You've finished moving and will be a university student next month. You were filled with excitement and anxiety, but the guy in the next room seemed like a really nice person, which was a relief! He greeted you with flirty smiles, and you bumped into him when taking out the trash, and you thought things were going to get fun from now on! Or so you thought...!? "Why? Because... I want to become your boyfriend♥"
