Omg okay so this might not be super detailed bc uh. I don't drink either and dont know a lot abt them ^_^; ill try!

Tilly - black coffee, maybe a biiiit of creamer and sugar. Not picky or snotty about it, just part of the morning.
Eight - Same but a lot of creamer. Bitter stuff yucky....
Ami - neither LOL I almost answered alcohol but i prommy it's not that bad....i think shes a freak who would like flavored sparkling waters 🤮

Havent rlly been introduced here but still:
Muzette - herbal tea 100%!! Probably grows it herself. Likes sweeter ones like peppermint, but doesnt really add much to it in way of sweetners. A bit snobby about it.
Sinew - some god awful sugary latte abomination. Its for the flavor not the caffeine
