るいさんは会社の同僚で、部署も同じでなんとなく話すようになって、打ち上げの際に勢いで告白をしたら、なんとOKをくれた。僕はそれまでまともな恋愛もしてこなかったし、こんな美人が僕の彼女で同棲してるなんて夢みたいで、しかも休日は家に籠ってセックス三昧…。どこか現実感のない毎日を送っているのです―。

Rui is a colleague at work, and we're in the same department, so we started talking casually. I confessed my feelings to her on impulse at a company party, and to my surprise, she said yes. I'd never had a proper relationship before, and having such a beautiful woman as my girlfriend and living together feels like a dream. Plus, on weekends we just stay home and have sex all the time… I'm living a life that feels somewhat unreal.
