Honestly I really liked this, haha. I feel like MC is now awakened to some new kinks she's into, lolol.
The only thing I didn't really like was the dark undertones of how the other girl got her injuries, when she mentioned she was at her grandparents place, it doesn't bode well about her home life. Or maybe I'm overthinking it and the mangaka just didn't really care about how she got the bandages but knew she needed them everywhere
But really if it wasn't meant to be sinister, it could've been a car crash or something, idk. Just a little unnerving
