Okay so how would the RO's react when mc one day forgets to give them their daily kisses?
Caemon: He wouldn't react immediately, he would watch the MC for a while to see if this was happening for a specific reason or not. After coming to the conclusion that the MC just didn't seem to remember it, he would wait for the MC to be alone to remind them of their duties..
N: "I'm here for the kisses" they would randomly appear next to the MC after making sure they weren't interrupting Something important. "Looks like you forgot about it today, MC."
Theome: They'd be a little nervous about it trying to remember if they'd done anything to upset the MC. After not being able to think of anything that could justify the MC not wanting to kiss them, they would talk to the MC about it and feel a huge relief to know that the MC had just forgotten about the kisses.
Sostrate: She'd be pretty blunt about it after realizing that the MC didn't seem to have any intention of kissing her. Or that they didn't even seem to remember that they used to do it "You haven't kissed me today yet. Why?"
Tba: They would wait for the right moment (or what they consider to be the right time) to remind the MC of all the kisses they forgot to give them in the course of the day
