@nono177013 he can't. At least not with his current plan. The MC has been so wrapped up in hiding the murder that he has yet to question why Nobuto, who he knows already had a lover he actually cared for, was dating his daughter in the first place. His whole strategy hinges on the assumption that, to the syndicate, he and his family are just random people Nobuto happened to brush up against, and therefore will be let go if they can be convinced they are uninvolved in his disappearance. The problem is even if MC can convince the syndicate that he's innocent, they still are going to want his in-laws money, and they now have video footage of him dismembering a corpse.
@Nod ehh i think since ch1 MC knows nobuto is dating reika for his inlaws money, since he heard nobutos phone conversation about it.
And i think after this nobuto arc is over he will find a way to solve that problrm too. Maybe by joining the syndicate himself?
