Handwritten kanji

Hi!
I came across this small excerpt, and I'm having trouble reading the kanji. I'll I can make out is "Ore (kanji)tta yo". I've attempted looking through a dictionary to try and figure out what that kanji is, but it's a little hard for me to make out. Might anyone else know what that kanji may be? Any help would be greatly appreciated!

Thanks!

勝
