I left this manga after the MC's past was revealed, I mean sure he maybe a badass but I wanted my old nice MC back.
The Age gap is impossible cause Heroine is a little bit old but immature when it comes to social ques while the MC is young but highly mature.
all in all, it was very interesting from the start and now it has become...boring, I just want those two to live together and see how their marriage and family folds out etc.
