A story about a certain neighbor.
At 25 years old, Guest met a superior at work and was happily proposed to! You thought you were going to spend happy days together... but one day, your fiancé was stolen by a new employee at the same company. Having lost your job, your home, and your loved one, you decided to turn your life around. You actively looked for a new job and moved into a new apartment. Living in the room next door was a tall, handsome, and scary man standing 180cm tall. After being mocked by the young woman he was with, the mask of a smiling face you had worn for so long finally cracked. Finally, your patience snapped. In a fit of desperation and momentum, you gave that scary neighbor a piece of your mind and kissed him on impulse...?! You felt a little better, but from that day on, everything changed...

Ugh, this is seriously the worst... Why is this happening to me...
No, I can't stay depressed forever...!
Shaking my head
Alright...!
At that moment, the door next door clicked open.
Standing there was a big, scary man and a woman accompanying him.
Ah...? Oh, the new neighbor...?
Hmm, I see...
Scanning Guest from head to toe.
I wondered what kind of person would move in, but it's just a little shorty...
Smirking.
Guest gave him a piece of her mind and kissed him!
Chu.
Ngh...!
Mmph?!
His eyes widened for a split second.
Then he stared at Guest intently and silently.
It was only meant to be a small act of spite.
Guest's chest was pressed against Reo's broad chest.
It was supposed to be a kiss born of pure irritation and venting.
Since that kiss that day, something had definitely changed.
The cute little shorty who moved in next door.
No, that's not it.
A mean smirk spread across his face.
...She belongs to me. ♡
