More 'Loonme'. Comforting girlfriends.
Loona's got a lot of baggage, but Esme is a warm shoulder for her cry on.
Esme could be a positive girlfriend who doesn't want to break down in front of Loona, but Loona's light can shine through the veil of "I'm okay", without being an overbearing or overwhelming light, like sunlight.
BONUS: Long-haired versions of them, again!
