Felix and Hyunjin are best friends. Roommates. Each other's emergency contact and emotional support human. They kiss sometimes, sleep together often, and say things that would make most couples blink. As far as they're concerned, this is a completely normal, deeply platonic arrangement. They call it friendship. Everybody else calls bullshit. But when other people start looking at them like they've already skipped several steps - like they're far too deep into something neither of them is brave enough to name - they're forced to confront the possibility that whatever is between them has never been platonic at all.
