I really like where this is going. He is not the picture-perfect male lead, but that's the best part since it's boring otherwise. And it's not like he is extremely flawed either.
And she knows it all, it's not like he is deceiving her. So she still chooses to mingle with him since they have a common goal and sees the good parts about him in the process.
Oh, and looks like she will catch the feelings disease first 😂. Kinda understandable, since she never dated before and he is still in love with his sister so that will be quite the effort on her part. And that is good as well, how many stories do you see where the FL has to work for the ML's love? It's always the other way around.
@ItsHanabi True that. The small but delicious variations in their expressions tell their feelings perfectly.
