I'll tell you what, it is cute and adorable and fluffy. Especially at the beginning when they both fall in love with each other, and get to know each other, and they are unsure about how to approach each other with those feelings...it's a really good.
But it starts being weird when Ikumi starts to be really pushy and is forcing some sexual stuff which is really really weird...cause no matter if you were together or not, pushing your partner to do stuff they don't want is NOT ok, it was kinda weird for me.
