@Nami Feels like I'm talking to a robot. The curse is supposed to be a mystery and it's not my fault you're too daft to understand basic storytelling. This is honestly embarrassing at this point so this will be my last reply on this topic. Cheers.
we don't know yet that they've been cursed to fall in love. it could be a placebo curse. i think they've made it pretty clear that they don't know what the actual curse is.
This manga is only supposed to be 19 chapters long, so it seems an extra chapter snuck in somewhere. According to the table of contents, chapter 17 and 18 are supposed to be part of the same chapter, but I dunno.
On page 7 of ch 4, it's supposed to be:
"Alright" ----> "It's alright" (Kusakabe is turning down Hoshino's offer to follow him back, not accepting it)
and then
"what should i do if we come across a pervert?" ----> "what will you do if you come across a pervert?"
