He put a necklace on him and it turned into a colar
┑( ̄Д  ̄)┍

I never said that it's a necklace to others and a collar to them. But as you can see in the manga the dom talks about giving him something to show that the sub is his and he gives him the necklace. After that the doctor also sees the necklace he is wearing and sees the meaning behind that necklace (aka showing that he has a master) and in return shows him his collar that he is wearing underneath his turtleneck. When the sub then returns home the master takes off the necklace (which serves more like a replacement for the real collar outside of their home because the sub probably wouldn't want to walk around with a real collar on broad daylight) and the master then puts on the real collar. There is no illusions HONEY. These are just different items to signal to the sub that he has a master and maybe even to other dogs if they were to approach him outside (in case of the necklace since I think that the dom engraved his name and his address or something on it)

Is it really that big a deal or am i just stupid... its not like its a actual profession... whether he was serious teacher in beggening or not shouldnt matter... shit i dont thnk any of my college teachers were serious

the thing is their relationship is founded on a lie or ''joke'' that snowballed out of control and that's why Hojun is pissed because he was pretty much played for a fool. Even if Ahns' feelings became sincere afterwards he kept up the charade for so long and that's a pretty big pill to swallow. I like both of the characters but Hojuns' reaction is pretty understandable.

I dont get the whole relationship startd as a joke thng... a relationship startn as a joke would be going out with someone on a dare... this is not that... he found him over a ‘joke’ but he took his job seriously and researched alot n helped him in alot of ways... so how was it a joke... he did exactly what he said he would even if he was serious about starting... its not the same at all to me

you're looking at it from your perspective tho from an omniscient 3rd party point of view you saw the hard work Ahn put in and you can read his thoughts and see he didn't have bad intentions but Hojun can't, all he has is what he experienced and what ahn just told him and from his perspective and what he's heard, it all started with a drunken darejoke and that while he was agonizing about Ahn sleeping with other students ahn knew the whole thing was a farce and never told him that he didn"t have any other pupils. Anyone would feel ridiculed in a situation like that . MMmmmmm i guess its kind of a mix of feeling dumb and also realizing you've been lied to. Hojun came into the experience with an open heart and expected reciprocity(.ie no lies) he was also having a vulnerable moment while confessing his feelings so i feel like his emotions were amplified.
Dude fuck hiiimmmm.... even if u find him what you gunna do? Fight him? Date him? After what he did to your sister.... its only $6000 call it a lost n forget that dude tf
