Just my prediction not a spoiler.
I think since the MC doesn't live with his mom, it's going to take a bit before he finds out about the concert being deleted. I'm sure by that time him and his crush will be moving forward with their relationship since the plot is hinting at them going on the aquarium date. Once MC finds out about the concert deletion, he's gonna be down in the dumps about it. But I have a feeling the crush is going to eventually come clean about being the singer and he'll give him a private concert
Also, I bet that one celebrity dude is crushing on the 3 idiots not knowing they're guys
