The manga that I am looking for starts out with 3 siblings 2 girls and 1 that was raised as a girl but does not have a gender intill they fall in love but they are worried about what gender they will become. And also there is a princess book thier mother use to read to them. Also im not completely sure about this part but i belive they start wearing boys clothes and a boy confess their love. And the transformation into a gender hurts

Before i start im going to use numbers instead of names because i cant remember names
I remember this manga about a boxing trainer ( guy number 1) who meets this guy (guy number2) whos between 17 and 23 he was half Russian or German and he was fighting this guy i beleive he was a pachinko worker trying to get back money or an ex customer. So the (guy number1) takes(guy number2) back to (guy number1) place to make ( guy number2) into a boxer and allows (guy number2) to share (guy number1) room if (guy number2) stops smoking and selling himself. Latter on you find out that (guy number2) brother started to make (guy number2) sell himself because after there mother ran away there father left. And to leave this on a good note i also remember (guy number1) slaped or scratched (guy number2) and when he got asked about it he said that his pet scratched him. So if anyone knows of the manga im talking about i would really appreciate it if you would tell me its name
