This type of topic is usually handled very poorly in manga..
(even in bl, let alone in straight manga)
But this manga did a pretty good job ig.
It shows how sexuality can be fluid for some people, and it handled the situation quite respectfully.
We always see straight men turn Gay ..... What about gay man turns straight for a girl.
