Yuta (bottom) holds a grudge against Seunghyun (top) because 10 years ago he didn't keep his promise to get him out of Kinkaku and he had to marry one of his clients in order to escape. This event hasn't been shown yet but it's mentioned that Yakuza clan that owned the brothel dissolved due to an internal conflict and that there was a huge fight (flashback in ch 7 when Seunghyun asks Yuta "is it because I didn't come to find you that night?" - there's a brawl in the background). This is the night Seunghyun promised to pick Yuta up and take him to Korea. He didn't do that and Yuta was left alone, forced into marriage with much older man and abused by the whole family for 10 years until his husband's death. As for Seunghyun's crush, it's implied that he liked Yuta the moment he saw him and that there was a reason why he couldn't keep his promise but we will have to wait to see how it unfolds. In PB, a lot of people liked to pair him with his boss, but in my opinion it was more of a master-apprentice type of relationship (quite unhealthy from Seunghyun's side and a lot of people now speculate that Jaeil was the reason why Seunghyun didn't pick Yuta up that night).

Can someone pls recap all the situation that have happened from chapter 1 to 17. I’ve read all of that but still confused
