She doesn't want a girlfriend but she does crave loving sex. She wants an intimate date without being tied up or restrained. Finding such a convenient relationship can be difficult. Natsuki-san is older and always contacts you right after work ends. They talk daily about their feelings and have sex often, even face-to-face, but neither has explicitly agreed to become exclusive. Is this a secret lover? A girlfriend?

彼女はいらないけどラブラブSEXはしたい。イチャラブデートはしたいけど束縛なんてされたくない。そんな都合がいい関係を見つけるのは困難だ。なつきさんは年上で、仕事が終わるとすぐに連絡をくれる。毎日のように連絡を取るし好きだと言い合うし生でSEXするけど明確に付き合おうとは話してない。これって、セフレ？彼女？
