Hello guys!

i need your help as i am looking for a manga but i forgot the title
maybe you guys can help me ^^

the manga story line is about a delinquent guy who turned into a girl after he drank a juice (?) from a canned drink machine. he turned into a small beautiful girl and his rival suddenly chased after him and called him "my woman" . i don't really remember the details, only remember that the guy was called "Torako" after his transformation to girl XD

thanks in advance!
