When he arrived back in his country. Pretty sure he was labeled as a wanted criminal I think. I can't remember exactly but after the HQ having noticed his presence back they were on the look out for him. Especially when Taekjoo had met the superior who set him up. But the specific part where they met was when Taekjoo had to go undercover to the the hospital where his mom was at which I'm assuming had to do with finding out Taekjoo was a wanted criminal. The HQ agents were like guarding the floor where his mother was at because they knew Taekjoo would show up but they were taken out. When he went to her floor there were no guards because Zhenya had already taken them out. So Taekjoo finds Zhenya in his mom's hospital room sitting there. The chase happens after HQ finds out Taekjoo is there. So he runs with Zhenya. After evading the HQ. They stay at a lowkey motel. Where they end up fucking at.
What's crazy is that Tj is also crazy because SPOLIER
He did exactly that. He came back for seconds to get his lick back
