Everybody's talking about "winning this" or "winning that" but let's be honest here. Even if the mangaka somehow asspulls that the main dude gets successful somehow, for the past 20 chapters, he's been an unemployed bum who's barely passing his classes, practically homeless, and barely scraping by in school let alone life.
He's not a prize, so there's no "winning" if any of the women get with him and tie themselves to this sinking ship. If you really want those two to win, just pray that the main FMC passes high school finally to finish her father's research and pray that the senpai FMC gets a lucrative career and can support her family.
I doubt many of you would go for somebody who's unemployed, homeless, and not good at managing basic life things.
