The feelings didn't develop after the one night stand, but everything else I agree with u.
Idk it does feel that way, it may not be meant like that but I doesn't feel as genuine as you normally see, maybe because you immediately get rushed into the one night stand and then him almost immediately asking her to lift her skirt within chapter one, then after getting a bit more on the family dynamic - looking back there are the usual little signs you see w characters having a crush on each other like heavy blushing but it's just there's no build up if that makes sense?
I totally understand that, this manga feel rushed and has this unfinished feeling when it come to the almost non existing build up. It's very confusing, but from the last chapter that was updated, it looks like the brother has always been in love with her, but he thinks she hates him because of the way she talks. However the author has done a poor job at clearly expressing characters intentions in a way that makes sense and it does feel like mc and ml are lacking in chemistry. But yeah, I understand what your saying and I do agree.
U do know that their paren'ts adopted her because they saw that they fell in love with each other? but because our female lead can't talk properly because off her nerves he thought she was mean to him ╮(￣▽￣)╭
I didn't catch that actually! Tho tbh I do find that a bit weird as a reason to adopt, like they're a prospective bride (￣∇￣") though they treat her like a normal daughter ofc, on the other hand with that in mind that makes it even more odd how they end up dating - well it's not like it'll change the outcome, this is what the mangaka wanted so she'll end up with her 'brother', not for me but there's plenty of other manga anyway
that is the weirdest solution they ever came up with why didn't they just take him in as a ward or something ??? they didn't HAVE to be siblings if the author wanted them to live together but oh well we're here now
ughh siegmund shouldn't have been so forceful, but I still can't ship her with her brother - it just feels icky, I mean they aren't actually related but how they grew up together and how they even look similair,, and how these 'feelings' suddenly quickly developed after a one night stand it all feels wrong
