Seems he's never around other than to fuck him.
No you see, Taesung didn't know Sooyung left the building and snooped around the gangster territory. He thought Sooyung was staying at his apartment. He didn't know Sooyung was going full Sherlock outside. It's not a bluff, it's just bad timing, that's all.
Remember what Sooyung said before he left the building:
"I'll be back soon and in one piece."
I guess Sooyung himself didn't expect that his snooping around would turn awry.
TS to injured, (maybe?? hospitalized) SY :
“Something like this... it won’t happen again. Not when I’m around.”
Well gee, TS! That WOULD be nice if you were around... but WAIT!!! — You NEVER are around when bad shit happens, only do you arrive at the END of it all.. so literally speaking, what you just said is quite literally a bluff.
& the latest raws just prove my point.
... But, I still find you the most attractive looking,<3
