Well, been thinking, here's my prediction:
It would be far too easy and convenient if everything got resolved next chapter but if things go too hard in one direction then there's no way to revert it, MC is going to botch it at first and Sakura will start leaning into Yuma, maybe they kiss but certainly no actual sex.
Eventually MC catches wind of this, has his own RAG Kazuya moment and realises he fucks up and glasses girl encourages him to and patch things with Sakura, the day is saved until an avengers level threat in the form of an actual ugly bastard comes along.
Blonde girl will probably offer herself to Yuma or something to console him or maybe she tries to seduce MC herself to give Yuma a path to victory.
Either way, as funny as it would be for MC to lose Sakura through no fault but his own, I don't think that line will be crossed.
