Initially, Elio had a hard time grasping the concept of crushes since he was still in the emotionally-stunted phase of his childhood. Aside from him not fully understanding basic emotions, Ardyn had constantly advised him and the other decuplets to be wary of people being "too nice" to them, as they often have ulterior motives (i.e. currying favor to get in their family's good graces). Thus, Elio instinctively distanced himself from those crushing on him since such discriminate niceties were "red flags" to him; sadly, since he didn't understand how to properly respond, his actions came off as a bit coldhearted and crass.

However, during and after his emotional journey - where he began to explore his own emotions, Elio handled crushed much better than before; while he was still unsure, he would try his best to meet the person's expectations while doing more research on the elements of romance. It was... "messy" (for a lack of a better word), but it somehow managed to work out in his favor since those crushing on him were able to educate him little by little to the best of their ability. At some point, they came to realize that both they and Elio were still emotionally immature, and what the latter needed the most is a friend; they only had a crush on him because they deeply envied his talents, his unique physical traits (i.e. his hued silvery hair and gemstone-esque eyes), and how famous his family was. So, those crushes eventually faded - being replaced with a desire for a genuine friendship, which, surprisingly, Elio reciprocated fully because he was more familiar with the feeling.

From his TUA days and onward, after losing his virginity, appropriately figuring out his sexuality, emotionally maturing by incredible degrees, and being in an open relationship with his closest friends (i.e. "Best Friends with Benefits"), Elio handles crushes from others like a pro since he's aware of his own popularity. Since he's technically taken, he lets down those who have a crush on him easily - though he does express his genuine happiness knowing that he's loved by them and others in their position. Even his "crushes" are momentary and superficial since he's attracted to certain aspects of that person instead of the person themselves.

Briar is usually pretty smooth when it comes to crushes, as long as it's just a casual, possible short-term crush. She has no problem inviting the person for dinner or in a date and knows some pick-up lines. She's pretty casual about the whole thing because she has rarely experienced real love, so she sees it as an opportunity for a good time for both her and her 'crush'.

However, when she goes pass the 'casual crush' stage and realizes that she's actually, genuinely in love, she gets so nervous when talking to that person. She'd try to keep acting smooth as always but they can always notice her nervousness, and would try to take things slow as to not ruin the possible relationship. She gets so embarrassingly nervous and excited over any little thing her crush does that she can't believe that's a part of her personality.

Wily - No emotional intelligence to understand it, would just get sulky if he hasn't seen them for a while and would rationalize some excuse to see them. Once someone explained the base idea to him he'd just go "Oh, yeah, that's me with (crush).", even if he was right in front of them.

Polly - Would sneak around family responsibilities and her manager to spend time with them. Would ask their opinions on songs and try to get them to be there for her concerts, even if she needs to make up some excuse. Would definitely pull inspiration from them for her songs.

Phillip - Would ironically be less shamelessly flirty with them than he is with most people. He'd also go out of his way to help with things, especially if they needed a ride. Bonus: He'd respect the speed limit for once so he spends more time with them.

Sivrit - Would adopt the same polite/honorable attitude he has in his gym to his crush and only to them. Would still get mad at everyone else.

Estella is pretty flirty and TENDS to make the first move. She's a real go-getter when it comes to crushes, and she handles the casual girlfriend deal just swimmingly. She's confident, witty, charming, and can even be sultry. Upbeat yet competitive! Loves to do adventurous things with a partner but can even be cool with just hanging around at home for the night.

Its when things start to get more and more serious that she gets nervous. She REALLY likes the guy and is terrified she'll screw it up now that they're close.

That said, she becomes quite the sweetheart the more serious the relationship is. She's real supportive and loves to see her partner happy. Estella is also really encouraging towards any personal goals her partner may have, as she knows how disheartening it can be to have those close to you try to discourage your dreams.

Arryn and Stahl married their crushes x
Ok, serious answer is that because of their jobs, the two often go months without seeing each other which can be difficult to say the least so they make what time they do have count and make it perfect. The distance is why Avian is an only child and grew up a lil lonely instead of having 5 siblings.

As for Avian himself, he doesn't want to be a burden so usually just be kind to them and help because he wants to rather than because he has to. He'd be too worried about hurting the other person to initiate. However if the other person was to initiate he'd probably be flustered as hell but not say no~
