- so we all know Grisha is a doctor in canon. i totally see him as a board-certified neurologist, and of course he's loaded

- and that's why Eren is just so used to the finer things in life

- though he didn't go to expensive private schools (Carla insisted on sending him to public schools cause of 'wanting him to live a normal life'), he did go to those country clubs with his father, where he learned how to ride a horse and play polo and you know, luxury stuff like that

- and while his classmates and their families went to Hawaii for a summer trip, his family would fly to Cancun to their summer house

- oh and his clothes. his closet consists of plain t-shirts in black, white, grey and of course olive ('the color matches your eyes honey', says Carla), sweatpants also in those colors, some white shirts, pants for special occasions. basic things like that

- his college roommates thinks he's a frugal boy looking at his closet lol. but once they know that boring plain white t-shirt is from acne studios and costs 250 bucks, and Eren has like... a dozen of those, they all shut their mouth

- one time he went out partying, wearing a white collar shirt and got puked on (don't ask me why or how lol). the culprit insisted on giving him a new shirt from the same brand. Eren be like 'yeah fine ok if you insist'. and it was a Thom Browne shirt that costed 500 bucks lol

- Eren who dresses like a loser but is actually rich and smells fucking amazing and is well groomed :))

- accustomed to the help. 'the help' here means service workers, like waitors or bellboys. he's not arrogant, he's just so used to be surrounded with maids and servants. while others might feel uncomfortable or awkward, Eren just casually bids them a soft 'thank you' without looking up when receiving the service and continues with what he's saying

- extremely polite and excellent table manners. it's like... everything is in his blood. never drops a untensil, always sits with his back straight, knows all the cues and signs

- idk i just picture him as a kinda guy who buys his clothes in dozens to save time and buys random stuff online for a ridiculous amount of money because 'it looks so cool i can't stop myself'

- went on a roadtrip with the gang and they stayed at a business hotel and Eren called the receptionist to bring him an air purifier because he couldn't breath :)))) and surprised when the receptionist was like 'what we don't have it here sir'

- takes Mikasa out on a fancy restaurant and Mika be like 'this is too much 'Ren the diner near our dorm is fine' and he's like 'my family come here once every 2 weeks'
