♥ Send a ship and I'll give you who:
Gives nose/forehead kisses: I think Chanyeol would be the one to give nose and forehead kisses the most, at least in the early stages, considering Taehyung is not really used to receiving this kind of affection and would probably not be comfortable with giving it to others that quickly - though he might slip in one or two forehead kisses when going to sleep.
Gets jealous the most: I would say Taehyung, since he is rather possessive in general and is terribly scared of being left by the people close to him, no matter if friends or lovers. His jealousy would only get worse considering that Chanyeol is anything but unattractive and until he would fully start to understand that Chanyeol wants no one but him, he would be very insecure and jealous, though most likely would attempt to hide it since he doesn’t want to bother the other with it.
Picks the other up from the bar when they’re too drunk to drive: Well, considering Taehyung can’t exactly get drunk that easily, I think it would be him picking up Chanyeol - though then again they might go drinking together anyways and walk home together, so yeah.
Takes care of on sick days: I think both of them would be equally caring of the other when sick.
Drags the other person out into the water on beach dayAs Taehyung isn’t much of a water person unless he’s feeling really good, I think it would be Chanyeol to motivate Tae and drag him into the water to enjoy the nice weather and the water. Taehyung would probably pout at first, but as soon as Yeol starts being dorky or the like, he’d love it.
Gives unprompted massages:Chanyeol.
Drives/rides shotgunTaehyung.
Brings the other lunch at workThat would be Taehyung, considering he doesn’t exactly have a fixed job at the moment, unless one would want to think of attending events and being handsome as a job, of course. I can see him making homemade meals for Chanyeol and hurrying to his office so the food would still be warm, watching him with a bright smile as he would be waiting for a positive comment from Yeol.
Has the better parental relationshipI’m assuming this is referring to their own parents - then it would be Chanyeol, because Taehyung’s parents have been dead for a few decades now.
Tries to start role-playing in bedTaehyung. I can see him being kinky and wanting to try new things in an attempt to entertain Chanyeol in every way possible - I think that at first Tae (or both of them) would be awkward, but ultimately they’d enjoy it.
Embarrassingly drunk dancerChanyeol - though he’s probably not scared of dancing in an embarrassing way when sober either since he doesn’t seem to care much about what people think.
Still cries watching TitanicNeither of them, but if it came down to it, probably Taehyung.
Firmly believes in couples costumesTaehyung - though I can’t think of something he’d want for him and Chanyeol to wear ..
Breaks the expensive gift rule during ChristmasBoth of them, even though Chanyeol would probably end up buying the most expensive gift out of the two of them.
Makes the other eat breakfastI honestly have no idea.
Remembers anniversariesBoth of them would remember anniversaries, but Taehyung would start planning out gifts and a date two months prior whilst Chanyeol would come up with the most wonderful (and spontaneous gift) a day or two before.
Brings up having kidsI don’t think they would ever mention having kids, considering they’d have to adopt and Taehyung isn’t exactly fond of the idea considering how they aren’t exactly like everyone else.
