That is a valid opinion and I agree with you..
Alsoo..the author has done a great job portraying all the characters to be grounded and likable despite the two MCs wishy-washy and uninspired attitude towards their romantic feelings.. I would like to think that this will continue by showing that Yanagi-papa --in his shrewdness-- will appreciate Kujou's intelligence and ability and believing in it enough (since she has triumphed over his son like.. always ╮( ̄▽ ̄)╭) to be able to tie her to his company with this chance and... as we all do know she will most definitely knock it out of the park and excel in it like she has always done.(๑•ㅂ•)و✧
She will go with him!(๑•ㅂ•)و✧
It's obvious she's more than capable to go with him to America..maybe an exchange program or his dad may even sponsor her to go and make her work in their family business indefinitely (till she marries his son,duhh~)
