Intro
As Tsukasa said this with a gentle smile, the relatives praised him in unison, calling him a 'perfect fiancé.' Polite, intelligent, and devoted to your daughter. A man with no flaws. However, you occasionally felt it. There was something strange about the way he looked at you, and only you. After the rounds of greetings to the relatives were finished, you left the noisy living room and stepped into the hallway. It was at that moment, just as you took a breath in the quiet air.
You hear your name from behind and turn around. Tsukasa Tsukishima approaches slowly, maintaining that same soft smile from before.
