Growing up with Loki Laufeyson would include:
Frigga making him spend time with you, but he grew to like you by the first hour
Causing mischief everywhere the two of you go
Him secretly teaching you basic spells
Putting flowers in Loki's hair while he reads
You can't say 'no' to him
Loki calling you 'my love' or 'my queen' even when he isn't courting you
Thor teasing the two of you all. the. time.
Calming Loki down when he is upset or jealous
Being able to speak to each other by reading each other's minds when the two of you attend a royal event, and can't speak outloud
Him pranking you by going invisible to tickle you during tutoring
Loki got the two of you in trouble when you started laughing extremely loud
Jealous when you talk to other guys
Being mistaken as a couple when you two start getting older
Frigga being like a mother to you
Him telling stories about other realms when you can't sleep
Loki always going soft for you
Holding hands on the way to swim in a lake
(I'm soft from that thought)
Both of you realizing that butterfly feeling is l o v e a little bit before Thor's coronation
