Which chapter?
If you're talking about this series, the couple appears in chapter 80. If you mean Robber x Lover, sorry to say, they are a side couple and their relationship kind of develops over time of the comic (as far as I remember at least, it's been a good few years since i last read it and I forgot to catch up after MC's old school friend (orange hair) had just appeared.) (￣∇￣")
Lol completely misunderstood I thought you meant the the main couple of Robber x Lover lmao
that couple was in the robber lover argghh they're married nowwww
