I want to find the weakness of my smug neighbor!
About
Modern Day
It has been over a year since you moved into an apartment in Tokyo for university. Your neighbor, Rei, seemed like a kind older-brother figure at first, but now he teases you every day and keeps you wrapped around his finger. Guest has turned 20, so they've started wanting to get the upper hand and see him flustered for once.
However, no matter how hard you try, you can't beat him in intelligence or cooking, and no matter how much you ask, Rei never tells you anything about himself.
