How about because of dabihawks week, answer that one for the ship game for me.
Who is the more clingy one?- Thanks to their jobs and the time they spend away from each other I doubt they're all that clingy, but Dabi is DEFINITELY a 'I'm gonna cling to you like a sloth' kinda drunk, especially when they haven't seen each other for a while
Who is more likely to admit a mistake?- They're both stubborn as shit but they'd eventually tire out and admit it at the same time
Would they lie to make each other happy?- Considering the fact they're both lying to each other constantly (Keigo is a spy infiltrating Dabi's group & Keigo doesn't know anything about who Dabi really is) Yes.
Who is more spontaneous?- ABSOLUTELY KEIGO Whenever Dabi's waiting for him to share information or just a meet up Keigo will surprise him by swooping down and picking him up in his arms and flying above the city. Dabi has motion sickness and probably throws up afterwards every time but Keigo still does it anyway
What do they do to cheer each other up on a bad day?- Every day's a bad day for them, so when it gets too much they like to sit on a random roof somewhere and drink while The Sad One vents to the other about why everything sucks. It's not ideal but it helps.
How do they describe one another to other people?- Both— "I have never met this man before in my life."
How are they both at handling money?- Considering Dabi's a villain who makes very little money, he's pretty good at conserving what he has, but Keigo's the number two pro hero so he has more money than he can count, but he never spends any of it for stupid reasons.
Who is the more romantic one?- My gut says Keigo but my heart says Dabi so I'm gonna say NEITHER since due to their upbringings love isn't something they're particularly experienced with
Lazy days or adventures together? Who prefers what?- They both prefer lazy days, since their jobs take up a lot of energy they enjoy laying around Keigo's apartment together and being domestic like a normal couple
If they had a pillow fight who would win?- Dabi because he'd light the pillow on fire and nearly burn down Keigo's apartment
Who plans more cute surprises for the other?- Dabi, except they're less 'cute' and more 'i broke into your house while you were at work and made some dinner oh also I broke like 15 plates.'
