Yayyy!! Thank you! I've been looking for this for the last few daysヾ(☆▽☆)
I'm looking for a manga about a delinquent boy main character that turns into a girl when his friend gives him a weird drink out of the school vending machine and then ends up having sex with his fighting rival that he's never won against! I need to find this! Someone please help!
