As much as I love this manga and the characters, you probably shouldn't aim to date your students, even if you're both adults. There's a huge power gap and not to mention, in this case, an age gap that could lead to an imbalance in a relationship. Teens/young adult women aiming for mature women happens a lot often than you think, but a mature woman going for someone younger IS problematic, especially in this scenario. Ever ask yourself why these women are going after someone younger and not a person more their age?
Now I'm not saying age gap relationships are bad, but it should be at a stage where you're both in the same place in life right now. That's why I truly respect Maria for resisting and asking Mei to wait 4 years, but "seducing" her throughout and leading the poor girl on, KNOWING that it isn't right, I found to be quite terrible on her end.
ugh if she becomes a teacher i hope she doesn't become like maria
