Eugene and hades:

Almost the same hair

Almost died

Dead mom (although technically hades mom comes back, he still had to grieve)

Bad reputation

Sad backstory

Secretly soft

That one ex

Rapunzel and persephone: _____________________

Kinda naive at first

Strong

Hair

Magic

Happy-go-lucky on the outside Semi-secretly has issues/trauma

Overcontrolling/protective parents

“Need to be good enough/liked”

Brings the soft side/good out of the emotionally guarded man

Confronted with “that one ex” and actually ended on neutral terms even though they originally “extremely disliked” eachother

Has a definitely not straight(okay well in cannon both sexualities are unconfirmed) girl best friend who is kinda… sharp , personality wise

Sheltered childhood

Plot wise/both: _____________________

showed interest at first meeting but didn’t fully act on it and formed a friendship before both sides had real strong feelings

Post-proposal issues

Met on accident… in awkward situation

Make some sort of “I owe you” deal

Dancing

Back and forth saving eachothers lives

Actually care about what the other wants
