Maybe it's better for YOU to put this webtoon on hold or dropped it if you don't really like the personality of the MC. There's another strong Female lead MC webtoons anyway. Such as The Way to Protect the Female Lead's Older Brother, The Villainess is a Marionette, Priscilla's Marriage Request, and possibly more.
I agree when someone said "she was startled and didn’t know how to react to his sudden movements so pushed him away and slipped. it was more of a way to show that she’s not entirely sure where his affection comes from and it scares her. and, in turn, it makes him think she’s uncomfortable with him and doesn’t want him to touch her."
If you don't like that then just dropped the webtoon. I personally enjoy reading this webtoon and the point of the matter is, I'm having fun reading it. If you don't find it fun or felt frustrated then just moved on.
HOW COULD THEY HAVE SEXUAL TENSION BUT ENDED WITHOUT THEM ACTUALLY DOING IT?! WTF
