It's so cuteeeee, i like it so far but MC still quite passive for my taste (i like MC with i'll step on you energy so haha).
It's to be expected for her to act like that because of her childhood, but i personally think somehow this type of ML would be really fun if it has a quite straightforward and more daring MC, but well we just started, i'm looking forward for characters development!!
Also i don't think this story need a second ml or villainess because there are plenty rooms to develop their relationship without using external factors such as jealousy with third party. Giving how she understand his thoughts it would be a great way to make them to open up for each other.
