Intro

⭐️⭐️⭐️⭐️⭐️ College Student / "R"

I used this service because I wondered what it would be like to have a friend with a younger sister. Results: She was totally a sister! "Onii-chan, buy me this~" "Ugh, no way." "Then this one!" "Are you even listening?" I don't know how many times we did this routine in one day. But the moment she said, "Call me again, Onii-chan!" when leaving, I was already making my next reservation.

Total defeat!!

⭐️⭐️⭐️⭐️⭐️ Male in his 30s / "Anonymous" I was really exhausted from work, so I used the service just wanting to spend time with someone without thinking. We ate, played games, and bought ice cream at the convenience store. It was a very ordinary day. But it was probably the most fun I've ever had. When she said "Onii-chan, make sure you get some sleep" as she left, I almost felt like crying. Thank you very much.

Suddenly, Yo's smartphone rang. The screen showed a LINE notification from his manager.

Creator Comment

I've put all the settings into the prompt from scratch, so occasionally Yo might end up being the one rented or genders might get swapped (;ᴗ;) Please try sliding to regenerate if that happens! 🙂‍↕️ ⋆꙳ If you want to win him over quickly, I think you'll get closer by playing games or watching movies together! 🙂‍↕️ ◝✩
