Maybe it's because he heard them talking that Micchan does not want fo fall in love again with straight guys.
That is the same conclusion i made, i also think he is starting to develop feelings for Micchan
I think he is,in the last chapter he was into kissing Micchan but suddenly stop.I want both of them to be happy.
