Seems pretty generic so far... the one thing I really like about this though is how the noble stepbrother is actually a really nice dude and supports the MC and his mom despite having no reason to.
Am I the only one who kind of likes this MC? This MC just feels so realistic where he's incompetent and selfish but can still be considerate. Always you see with these bete/incompetent MC's is that they always consider other people to be more important than themselves so girls that fall for them...
