I feel like ML is not really invested in the relationship as Gunjoon does, when they're together or when we get to see Jungseok's pov it's always "I shouldn't have gone too hard (on sex)" or "Sex is good. We're really compatible" and it's clear that he's just there to have fun. But for Gunjoon, first he doesn't want to have sex with somebody he doesn't like and he even had a rule before that he will only have sex with his bf once they reached 100 days together. And while reading the story, it's clear that he likes Jungseok but was right that they view this relationship too differently. Aside from that, the rumours + ML's ex-fubu really affected him and was unstable before the confrontation. I think all Gunjoon needed was assurance, at least he will feel 'liked' not just someone who you just wanted to have sex with.
