Okay so I think I've figured out Seonwoo's problem. I went back to re-watch and make note of who called whom and who everyone had been on dates with and realised I had completely forgotten what happened with Seonwoo in the first episode.
Seonwoo was crushing on Junsung!!
They did the washing up together after dinner on the first night. There was some playful banter and SW started crushing on JS.
SW's first phone call was to JS. JS answered in front of Sungho but wouldn't tell him who called. SW got 3 calls that night but JS wasn't one of them.
SW stated his type is someone who takes the lead and makes the first move. JS very much is this type and stated he has dated everyone he's ever been interested in (our boy is persistent). SW likes this. SW wants this. (Yoonghee also fits this type but SW said from night 1 that his only feelings towards YH were pity after receiving his phone call).
SW starts to get his pride hurt knowing he's popular in the house but not with JS. SH picked SW for the first proper date. Before the date, people start speculating on how much time JS and SH spend in the bedroom with the door closed. SW finds a reason to interrupt them. I assumed that this was about SW hanging out with SH but after the re-watch, it's clearly about SW's interest in JS.
SW makes a comment that he has someone he's interested in but he will try three times and if they don't reciprocate then he'll move on. (Very practical especially when you remember that he only came out about a week before the show started) JS never responded to any of SW's flirting or the phone call. So SW took that as his sign and gave up. So now he's untethered, and reassessing his options. There are three openly dominant men in the house (SW's type). They are: Junsung who isn't interested, Minsung who SW views as a friend, and Yoonghee who SW isn't attracted to. His options are fairly shit so it seems he's sort of given up. He persists in going on a date with SH because their date got cancelled and he sees it as the polite thing to do even though he spends the date telling SH how he's not his type and seems very surprised during Jenga when SH says he wants another date with him.
But then he seems to decide to fight for JS. He sits down to discuss things with JS and is surprised to find out JS is set on SH and sees SW as a rival. He brings this up a few times afterwards, in what I first thought was just a dick move, but now realise was SW's way of trying to restart the playful banter from day one or at least get some of JS' attention. He severely underestimates how serious JS is about SH.
At the bbq JS gives his coat to SH. SW then goes and gets a spare coat that he left on the couch by the door. He catches JS in the doorway and offers him the "conveniently available" coat. JS straight up rejected it then told the camera: I gave my coat to someone I like, I'm not then going to wear another man's coat. And proceeded to freeze his balls off as a matter of chivalry.
In conclusion Seonwoo coming across as an ass because he has no chance with the one guy he actually likes and he knows it. His pride has been hurt and now he's just going through the motions. He hasn't mentioned it since the first day, not even in the private interview bits, which tells me he really likes this guy. Personally I think he's not saying it is because he knows he has no chance and is trying to deal with damage control of how he's presented on the show and I don't blame him. I would do the same, honestly.
I was all set to hate him as a player or a heartless prick but now I just feel sorry for him because I, like everyone else, am hoping for 2sung pairing.
