Ahhhh... Nevermind...
I just looked at the raws, and what I wished for isn't gonna happen... 〒_〒
Wait what, what happened?
Beware 'coz I'm gonna spill all to the very last chapter..
SPOILERS :
I don't actually know what was happening since i don't really know how to read Korean..
I just literally scrolled through the chapters.
But from what I can tell...
When I wish for the Hyung to fall in love with YeonHae and regret whatever the hell he did to the boy, that's never gonna happen because the Hyung was being an asshole up to the end of the chapter.
He even flirting with the Teacher just to piss off his lil' bro. And went as far as to give the necklace to the teacher.. (what a bastard!!)
YeonHae saw the teacher wore the necklace, and cried, alone on the sidewalk.... Poor babe (╥﹏╥)
However there's a new character showed up.
A blond boy (probably a relative or an acquaintance of the blonde girl who's pretending to be TaeGyum's girlfriend. I just made that assumption because they show up together in front of TaeGyum.)
YeonHae's first impression of the boy wasn't that good. (He probably thought the boy was bullying or dragging TaeGyum around, so the boy managed to get himself a fly-kick on the face by YeonHae. Bwahahah!)
So long story short, whenever YeonHae was dishearten by that Hyung, the boy was there for YeonHae to lean on. From friends, they both become fake boyfriends, and then they go out together for real ε=ε=(ノ≧∇≦)ノ
The boy bought a pair of studs for couple, to replace the memory that YeonHae have of the damn necklace.
I could tell you more, but it's gonna be a loooooong ass essay. So that's the shortest summary I could give for now. Ask me anything if you're curious about something. I'll try my best to answer. (▰˘◡˘▰)
Ooohh tysm for the spoiler
Man... My heart broke when the Hyung snap away the necklace from YeonHae...
Ughh, for the love of Yaoi, I hope he's gonna fall hard for YeonHae and then regret it later on for being such a douchebag.
