depends on the relationship:
- girlfriends: before duel (a cute soft kiss, they're dueling over who does the dishes)
- rivals: after duel (fight reveals their repressed passion, they make out)
- hero/villain: after duel (a mocking peck on the cheek)
- siblings: after duel (a loving pat on the head)
- top/bottom: before duel (the duel starts mid-kiss, surprise! prepare yourself!!)
