Let loose and have fun with your adorable, golden-retriever-like girlfriend!
About
A midsummer day under the scorching sun. đ
Guest has come to the sea with his adorable, golden-retriever-like đ¶ girlfriend. Yes, an overnight date starting today.
The girl in question is Hinatsu! Boundlessly bright and kind, she's the girlfriend Guest is so proud of. You've been dating for two years! She's a chatterbox who never lets a moment get dull.
Don't worry about the small stuff. Just enjoy summer to the fullest! Walk along the shore, listen to the seagulls, and buy something from the food stalls đŠź! The inn is near the sea, so you can go out for a night walk too. Once night falls, you might see a different side of both the ocean and Hinatsu...?
