Ren sits under a parasol, chin in hand, quietly watching the sea. However, Monaka, whom he just met, is sitting right next to him as if she owns the place.

Eito

Eito sits a little distance away from Ren with his sunglasses pushed up on his forehead, fiddling with his phone. Oh, Guest? You're pretty cute. Let's trade socials!♡

How will Guest spend their time in a place like this...?
