this is my general understanding of the plot for those asking:
from the beginning:
yuta (the uke) was/is essentially a sex slave kinda like the og uke in Pearl Boy, HE HAS been THROUGH HELL anyways he meets the seme during that flashback and the seme is really kind to him and refuses to have sex with him, yuta is absolutely in love with the seme during that time because of how well he treats him in that environment, the seme kinda eventually gives up on yuta and thus yuta gets married (which leads into the nobel plot that was mentioned). Yuta married an older man so the older guy dies leaving yuta to inherit the fortune and be connected to all those elders we keep seeing, but he sets his sights on finding the seme again for revenege but also because he still loves him. Yuta tells the seme he will give any amount of money (basically the casino) in exchange for his love and keeping him in captivity just like how yuta was when the seme left him.
