Marguerite, Eros 3, Agape 4. Vasile, Ludus 2.
Eros 3. How do they feel about public displays of romantic affection? Does it make them uncomfortable? How do they feel if a romantic partner kisses them in public?
Oh she'd be so nervous about it. She would enjoy it, but having people around her watch would make her flustered to the nth degree. She's good at hiding it for the most part, but she has a limit before she'll try to flee from embarrassment. If someone kissed her publicly, I think she'd die inside from everyone watching her, so best bet is for private displays of affection.
Agape 4. Does your OC have a religious faith which emphasises the importance of a love for all people? If so then do they try to follow these teachings authentically? Or do they just pay lip-service to them? If not then do they follow a more martial or mercantile faith? Or none at all?
She was raised in it, but she does not personally believe. However, because she was raised in it, it plays a big part of her values regardless of her belief in God or a god. While her mother donates to charities for like tax write-offs, Marguerite would be more likely to buy a homeless person some food (or clothing or something else) or even donate to a church. Religion wise, she's an atheist.
Ludus 2. Is your OC particularly skilled at flirting? Have they had to practice this or does it just happen naturally?
Not in the slightest. He would not be able to flirt effectively if held at gunpoint. He would die. He can talk to women normally, but he simply cannot flirt without sounding awkward. When flirting comes to mind, all he would be able to think of is bad pickup lines, and he wouldn't want to subject any woman to that. Plus, his friends would tease him relentlessly. He'd just be more straight forward like "You look pretty." "I like your hair." "I like your singing voice." "I brought you flowers." On a scale of 1 to 10 his rizz would be like a 6 or a 7.
