The MCs in The Egg Project are insufferable

I've seen Webtoon promote this story once in a while and a few days ago I decided to bite and binge read the series to its newest free episode (ep. 46). I can confidently say Riku and Cherry are two of the most insufferable MCs in any story I have read.

First of all, I find their dislike of each other as completely petty. They're high school seniors but act like kindergarteners. Why do they still talk to each other? Clearly their moms gave up on them being friends, Riku and Cherry hate each other, and have no mutual friends or hobbies. They could just grow up and ignore each other's existence.

As for their forced partnership they both understand they have to pass, Riko to keep his dad off his back and Cherry to graduate. Yet, they both ignore this most of the time. They have to do activities together with the egg to earn points but can't sit down together for more than a minute without fighting. They had a dumb argument about who would take the egg home on any given day, the most dumb part being Cherry saying he can't have the egg the days he has volleyball practice because the egg could get hurt... don't they have locker rooms???

Now the most annoying part is whenever one of them gives the other a genuine compliment or tries to have a heart-to-heart the other one either makes a joke out of it or insults the one giving the compliment/heart-to-heart. This makes the one giving the compliment/heart-to-heart mad, hypocritically mad because they do the exact same thing when the roles are reversed.

I also don't understand how Cherry developed a crush on Riku. Cherry hasn't realized he has a crush on Riku, but he clearly now does giving the blushing on awkward around Riku.

So yeah, I don't like these two characters or their relationship. If any fans of this series can tell me what I'm missing, I'm all ears.
