This is just a simple fan art doodle of Charlie Morningstar & her Ex-boyfriend, Seviathan Von Eldritch, having lunch together so they can be Friends. Even if Seviathan made an appearance in the actual series, I would imagine (If So) him being less hostile as his Family, the Von Eldritch, and that if the Morningstar's & Von Eldritch's made these two into an Arrange relationship, leading to an Arranged Marriage, so that the Two Families' companies and join forces together (including the Hotel).
