I get what you mean but I feel like their personalities are both kinda straightforward? Like, they ask a question or have a problem and need to find the answers/solution to them right away..
PROACTIVE!! That's what they are! and practical. At this point, it's clear to see they are both content with their own characters, and don't feel a need to change/develop. So, they won't waste think on the fluff, especially since they don't believe in the fluff, so they'll jump into the deep end without realizing how dangerous it is... I don't know if I'm explaining it right.

yeah... that might be right they are acting threw a little experience.. he because his family issues demand it and she because some jerk put her thru a lot.. and they don't think there might be more than just 1 jerk and what other's doo.. i think they suit each other.. but
.. i still think the author should give us some more first, than fan service #-.-)

i think she just wanted to show us her poor dress.. and her stocking's fixed by her.. that might talk bad about her as a noble woman and she don't want to look pathetic in front of him.. still i think it should be in a different way ヽ(`Д´)ノ
he will probably will buy more stuff and put rose more envious .. that would be good to see(๑•ㅂ•)و✧
please... i was expecting for both of them to be more stoic in their relationship, and if it had to develop it would be slowly but these is too much!!... i hope she can be an amazing MC strong and powerful.. i want for her to show she can do that and more, and not start to fall in love at the beginning these is way too awful(╯°Д °)╯╧╧
note: idc about sex just the "badump" it's like they will start to wonder why their heart beat, i want the character development be first and the love in second motion ┑( ̄Д  ̄)┍
