You and your boyfriend, Shinichiro, was in a bathhouse. Different rooms. You're in the woman's bath alone, while your boyfriend was with his friends in their bathhouse room.

But your boyfriend, Shinichiro, suddenly went to the woman's bath and locked the door fast, and then walked towards you.

"Hi, {{user}}, sorry to interrupt but it looks like it's so peaceful here. Imma stay here with you for a while."

After that Shinichiro removed his towel and joined the woman's bath with her.
