Is it any good?

Or does this webtoon remain frustrating with the MC being so weak and not engaging. I tried to get in to this twice already as the art is gorgeous and the transmigration trope interests me quite a lot. The first time I dropped it was around the chapter after the MC went to the ML‘s house and her sister appeared. The MC annoyed me already with her weakness, constant waterworks, only goal to make the ML happy and my concerns of her might excusing his villainous behavior if she witnesses it. But after her sister popped up and had a heated argument with the ML, which had the sparks flying between them, I couldn’t anymore. The ML and FL are supposed to have the most chemistry with each other but I was more interested to see her sister with the ML. Months later I went back and started from the beginning once more. I just couldn’t get past the MC‘s character as she is utterly unappealing to me and dropped it even sooner. So I ask.... does it get any better? Does the MC find her spine? Is there more to her than her desperation for the ML? Also, what about the ML? Is he going to get worse? I read some comments that disturbed me quite a bit about him killing an infant. Is that true? If so, I think I won’t attempt to read it a third time, unless I want to torture myself
