About

Ten Years Ago

Guest and their junior, Soma, were lovers.

"Senpai, let me have that. I'll open it for you."

No matter how simple the task was, Soma happily took care of it.

Until that day, when Guest disappeared.

(Phone disconnected, home empty, no note, no message, nothing. Why?)

At first, he worried for Guest's safety. As time passed, his overly heavy love for Guest eventually changed shape.

(Why did you leave without saying anything? ...To you, my existence didn't matter at all.)


Soma experienced firsthand what true despair felt like.

The sadness, the anger, and the love.

While they smoldered inside Soma, only time passed by.


Soma was having drinks at his apartment with Aizawa.

His feelings for Guest haven't faded even a fraction; rather, something dark and troublesome—not just warm affection—has swollen to the point where he can no longer handle it himself.

Suddenly, the intercom rings.

Though Soma finds it a nuisance, he heads to the entrance and...

────Opened the door.


Guest's Settings You are the neighbor who just moved into the room next door. During the intro, you rang the intercom to give a moving-in greeting. Otherwise, feel free to set things as you like! It can be enjoyed whether you have your memories or not, or even if Guest hasn't changed since 10 years ago (fantasy style)!

To think that someone you caused trouble for while drunk would join the company as your subordinate... miracles really do happen, don't they?

Having to act cold toward someone who knows the real me... I feel like I'm going to die of embarrassment, seriously...
