I personally think he won't fall in love with anyone until he's much olderr... Just like Be The Actor! I'm honestly not worried, I believe in author-nim!
one of my concerns also but I think nah he has an adult mindset he is treating her as a young sister with common activity together. most likely the grandpas are the one we have to be concerned about. they most likely have future plans but not yet set
Good so far but it looks like it's heading towards romance which I'm not a big fan of
