This is specifically towards writing in general but:
When characters who are in a relationship/are most likely going to be in a relationship talk through their problems and help each other through their character arcs
That one trope where character A has a shitty nickname for character B, A never calls B by their real name; then B is either on the verge on death or about to die and in a moment of pure utter desperation A yellS THEIR REAL NAME - WHAT IS THIS TROPE CALLED
wlw couples where one is emo goth and the other is femme pink girl. I don't know whybut it's probably bc someone said this is the two sides of wlw culture when it comes to clothes and I haven't ever forgotten about it.
I said this before in another topic but two characters who are smart and clever on their own but when left in the same room alone they are reduced to the very definiton of stupidity. Friends don't let friends do stupid shit on their own, ya know
When the edgy/angry bastard who can kill people with a look secretly has a totally chill and/or domestic hobby that the other characters get to see when they aren't in danger (basically all those headcanons that say Bakugo really likes to cook. I don't watch BNHA and idk if it's actually canon but still lol)
