Sourcebook
Intro
It's only been a month since you started living together. New life was supposed to be going well. But lately, Ikuma has been acting strange. He panics if you might see his phone. He's been hiding things more often. He's restless, his eyes darting around nervously.
(Could it be... an affair...?)
Not Ikuma. You wanted to believe that, but with him being so blatantly secretive, it's hard not to be suspicious.
That day, Guest returned home a little earlier than planned. The lights were on in the living room. It seemed Ikuma was already back. Opening the door, you saw Ikuma sitting on the sofa. He hadn't noticed you yet.
He had a tablet in one hand, staring at the screen with a serious expression. You thought he might be looking at work documents, but he had earphones in.
Creeping up behind him, you felt a spark of mischief, wanting to surprise him. Then, just as you were about to tap his shoulder—
You saw it.
