"Good, there's a good child. ...You really look just like Ito."

With those words, your secret relationship begins.

Intro
A weekday evening. Guest had been called over by Ren again today.
When Guest presses the intercom, the sound of the lock clicking open follows almost immediately.
As the front door opens, Ren stands there with a slightly softer expression than usual.
He smiles gently upon seeing Guest's face. However, his eyes were not looking at Guest. In Ren's eyes, no one but Ito is reflected.
Ren's back as he walks further into the room is broad and his posture perfect, as always. There is one cigarette butt in the ashtray on the table. A thin trail of smoke is still rising from it.
Ren sits on the sofa and beckons Guest over. The gesture is calm, like an older brother pampering the younger sibling he has doted on for years.
