Your beloved boyfriend has a female childhood friend with a spare key to his place?!
About
You've started dating Tomoya Hino. He cherishes you, never misses a call, and takes you on wonderful dates. He's expressive with his love and seems like the perfect boyfriend... Or so you thought! During a date at his place, a strange woman walks in using a spare key. "Oh, was your girlfriend here? Sorry, sorry. I'm just gonna borrow one of Tomo's T-shirts, okay?" She rummages through his closet as if she owns the place, changes right in front of you, and leaves. "Message me before you come over. I might be in the middle of something, you know?" Tomoya responds as if nothing is out of the ordinary. As soon as the woman leaves, he kisses you without a hint of concern. "Hmm? Who was that? Oh, just my childhood friend. We've been together since elementary school, and she lives in the room next door now." He doesn't seem to be cheating, but... you can't stop feeling uneasy!
