Okay I got confused once again cuz translator said in their notes that “if he didn’t touch me in the first place” was not meant for the breast slap and groping scene when in fact it must be that all along. Yoohyuk (the guy with glasses at chapter 7, shaved part on one eyebrow) is the one asked for the shampoo and snickered and slapped gyeol’s breast after seeing them. He then invited Jonho to also feel gyeol’s breast and when gyeol rejected them he got angry and used his seniority against gyeol.
Then the other sergeant, chanwoo (the guy who has moles, one near on his nose and upper lip, one on his forehead and neck) entered and said the “it’s not my concern” but then at night he sneaked at gyeol, groped him and r* him.
Yoohyuk was listening while gyeol is being r* and said “ fxking pervert, he was acting like he didn’t want it” Yoohyuk’s pertaining to sergeant chanwoo here.
Yoohyuk’s bullying became more severe, he mocked his speech disability, called him sheep and even covered up his colleagues that kept on molesting gyeol. Idk much about military but maybe gyeol is under yoohyuk’s command and he allows his co sergeants to use gyeol as they please and mock him after.
In conclusion, when gyeol said “ if he didn’t touch me in the first place” was about the time when Yoohyuk slapped his breast and invited Jonho to touch him because that’s where all began.
We can also assume that yoohyuk also r* him later on.
Okay so I read it again and I think I’m right. First, in the bathroom scene, one of the person near gyeol slapped his breast after Yoohyuk laughed at it. The person who slapped it told everyone there that it feels like a woman’s. So Yoohyuk tried to grope him but gyeol slapped his hand away and that made him angry so he asserted dominance and that’s probably what gyeol was talking about “If you had not touched me first” that yoohyuk was the one who started the groping and the others did the same thing and even invited the sergeant chanwoo who told everyone that groping gyeol was not his concern.
The Irony, even tho he said that it was not his concern, later that night, he was the one (sergeant chanwoo) who sneaked in gyeol’s bed and was the first one who actually r* him. (Notice the moles. The guy who sneaked in gyeol’s bed has a mole near his nose and upper lip. That is sergeant chanwoo) The guy who was listening while gyeol was being harassed was indeed Yoohyuk (Yoohyuk’s main feature is his shaved eyebrow)
