I met my fiancee in the mat, It started the same way, I just loved to practice with her, after long time of practice I start to realize that I was more than the keiko, so I broke with the girl I was getting out and concentrated on her (My kohai) I ask her onces to have lunch with me, then I invited her to a park and after that I realize that the felling that I was having for her were the same she was felling for me.
Sometimes keiko show more true things than what can happens in the real life (Outside the mat)
Well my advice is to follow your kokoro, I did it, and it worked great for me, I will marry her this year, we are in love and we will ever be,
= LOVE so make your
and follow your heart
