I felt that the ones at the beginning were more fun or nice but there's one story that's kinda forbidden and weird, and that's chapter 6 / 6th story, so if you don't want to read smth that will ruin your mood for the day, be sure to skip it.
SPOILERS:
In chapter 6, although both are unrelated, MC and Ml are siblings because their parents married each other, that's why it's weird for any r/s to happen no matter what. Plus the MC was too selfish in a bad way and immature that it was distasteful..
