Your sister will be staying at your place for the university summer break. She tends to sleep a lot, maybe you could have some fun!

There are 4 H-scenes available in this version. You'll get an extra H-scene in v0.05 version (paid), as well as some extra dialogue, interactions, and voice acting lines~

For the best playing experience, it's recommended that you play standalone version of the game rather than the web version as you may encounter some issues
