About the MC
Despite the alleged revenge the MC doesn't like to use his ability (but he is weak compared to others) and always tells himself that he must prepare for the consequences once everything ends even to die at the hands of those who he use his ability.
The kingdom and the few restrictions towards the MC and the class
Basically the kingdom has measures against the bearers of skills and at the same time it's about winning the class, the MC makes his harem more focused on training so that they can survive what makes him a good piece for the kingdom.
Class guys
I just remember that they are looking for ways to win over girls, even not so good ways, some do not even train.
Class girls
Normal (?) but equally not all practice their skills.
