OKAY. let's clarify some stuff for people who are confused:

the entire episode is not a dream sequence. aside from that just being lazy, it's also not what the editing is communicating. this show is very good at editing in a dreamlike, slightly disjointed way; it's part of what contributes to it feeling so intimate and personal, and nothing about that editing really changed in episode 6 except for when it got dramatic RIGHT at the end, but i'm gonna address that particular tone change under the cut for those who want spoilers

the show intercuts flashbacks throughout, even dispersing flashbacks of what appears to be the same scene (therapy) through multiple episodes, and intercutting current dialogue with flashbacks (jaewon's brother flashbacks with his father's voice). the last five minutes MIGHT be a flash forward, which means that a lot of the coupley stuff left from the trailer could be coming up in episode 7 either as a lead-up to the inevitable or afterwards in flashback form, but again, i'm leaving my personal thoughts on that for under the cut

ALSO, he definitely says "boyfriend". he says "남자 친구" which literally translates to "namja - man, chingu - friend" and used together like that is the colloquially understood term for "boyfriend" in korean; it is sometimes shorted to "남친" (namchin) but BLs haven't reached that point yet. REGARDLESS, even though that technically translates to "male friend" SO DOES FUCKING BOYFRIEND. the only other word is "애인" (aein) which you may have heard, but it's gender neutral.

the context of that interaction is important. he says friend, the attendant clearly notices the implication and says "oh a girlfriend?" and he responds with "no, a boyfriend" and then the cashier gives him romantic fireworks. it was not an accident or a mistranslation. just because jaewon is closed off and masks does not mean he's like that about everything all of the time. like he says to jihyun, its easier to talk to him because he doesn't know his baggage. and as somebody who is very similar to jaewon I find it so easy to say things to strangers that I struggle to articulate to my friends. I come out to people as soon as I meet them but coming out to my friends was hard. it just be like that sometimes.

the last thing is a spoiler of what's actually happening in that last scene in relation to the movie version of this show that came out, so if you don't want to see those, simply do not look under the cut:

jihyun is not dead, nor is he a figment of jaewon's imagination. it is not a dream sequence or a fakeout - jihyun does almost drown and it does utterly fuck jaewon up.

that is literally the only spoiler i know from the movie because i saw it by accident and then noped out of the comments section of MDL and banned myself from going in there because i hate being spoiled, but it's actively starting to worry me just how many people are convincing themselves that it's all a dream or a fakeout who are going to be really distressed next week when it turns out not to be.

i'm all for collective fandom delusion (i was in The 100 fandom for years) but this seems like the kind of thing that, as somebody who is also a mentally ill queer person who gets WAY too attached to media, could be really damaging to everybody the longer this week goes on without answers and the collective fandom delusion spirals out of control.

(and hey, maybe this spoiler is a lie, or maybe the show is being edited differently to the film, but i still think it's HIGHLY unlikely all of that was just to trick us for no reason. that doesn't really align with the story they're telling)

take a breath like jihyun can't and remember there are FOUR WHOLE EPISODES LEFT. maybe the show will end tragically or bittersweet but i don't believe they'll do that in a way that is designed to actively hurt us. this is a show made by queer people, for queer people, and they foreshadowed from the start that this was going to happen. it's not a dropped plot point or a fakeout or an accident of editing - everything is VERY intentional.
