- Top was heavily bullied in school and grew up bottom of the pack, that's why he absolutely loses it whenever someone calls him a weakling
- Top's parents passed away in some kind of assault and he's rationalized it so that they died because they were weak. That OR his parents were super abusive and called him a nobody and only saw worth in his accomplishments, thus why he's obsessed with winning and such a sore loser
- He probably had a grandma he treasured because he's extremely lenient when it comes to MC's grandma, he has a soft spot for the elderly
- Blonde dude is ML's frienc/classmate/bully from high school and he'll notice how obsessed ML is with MC and will try to take him away as some kind of payback or just to fuck with him
- Kim Dan will catch feelings very soon, there will be a whole story arc where he comes to confess his feelings, ML will do that whole "you're just a tool" shtick, MC will walk away and it's going to be very similar to the story arc in BJ Alex where the MC left and ML tried to win him back
- Grandma will pass away and ML will comfort MC genuinely
- Pervert doctor who molested MC will come up later and get fucked up by ML for trying to do it again
None of these are confirmed I'm just spitballing
