Ok, i know we're gonna get happy ending at the end. But, please, when Toui said "This will be last time", I, strangely, felt really relate to that situation, as if I was in there, felt their bitter and painful feelings, and actually that makes me sobbing so hard right now even when they look cheerful watching soccer as if nothing happened and casually making small talk in the car
Now i can continue read this manhwa in peace because i got a hint that yiyeon is not the one who betray jin kang (▰˘◡˘▰)
Be it black or vx, i hope yiyeon in jin kang's side
Its not like clear info. I just get a hint on last chapter when black questioning why Lrot disappear suddenly. I mean, he must know the reason if black and broker B is same person, right? So, i assume black is not the one who betray him.
Then on ch 10 or 11? I kinda forgot. But there's a time when yiyeon suddenly appear in front of jin kang's house early in the morning after black hack jin kang's program just cause "he had a feeling". I was certain yiyeon is black.
And, last hint. When black keep questioning if Lrot has lost interest in VX and how discomfortable he is when jin kang said the reason he's coming back is to find someone who (black assume) more important than VX. From this, i got the feeling if black and VX is the same person or if not, at least the same team. And he can be yiyeon, looking how fascinated he is to jin kang. His uncle also give a hint that yiyeon specially searching for jin kang as VX searching for Lrot.
So, consider all of that, i was certain that at least yiyeon in jin kang's side and not the one who betray him (broker B).
Hope my explanation can help you. And, remember, all of this based on my own conclusion. It could be different from what actually happened. So, lets see how the story going on~
It's heavy, yet wholesome
