Great, i wanna see how those 2 get together.
About Mika and the girl that fall in love with her (i forgot her name LOL) i think it was great that they didn't end up together, Mika clearly didn't felt in a romantic way about her, but started to create an empathy and a friendship, i am glad that the glasses girl did'nt end up alone, she loved her friend this entire time, poor girl.
I think Jin will introduce another older female character and Mika will fall for her, i don't think that will end on those 3 alone being friends, Mika deserves a hot, steamy, beautiful and nice woman that she can go madly in love, even more than her sensei.
