Yeah my take as well, he is second male lead as in the other guy in live with Yeongwoon posing a threat. Lmao YW have been in love with Seo In for 10 years or so, so sorry Taegu dude but no. As you said this is more of a plot device. To be honest you know i'm quite afraid. He would team up with Haeyool to hurt him, like have him jumped or something (remember first scene of chapter 1)
The old man doesnt seem particularly sus to me, in like that I dont think he's ever been the actual cause of harm to Yeongwoon, but i just dont like it because Yeongwoon clearly seems him as like an older familial figure. But ahjussi seems more like a plot device to push the main couple together more than anything. I just hope he doesn't get more aggressive or impose himself on Yeongwoon(which luckily he hasn't yet)
