What Hugo's plans were at the start: get married, train his replacement, become a court chef (that is, a cook for Sylvester's castle), live in the noble district with his wife.
What happened: his fiancee dumped him while he was working in the castle. (It may or may not have been her parents' decision, but anyway, the marriage fell through.)
Hugo's new plans: drown his sorrows in work, swear off relationships, become a court chef and move away from the lower city so he doesn't have to see his ex anymore.
Myne's counteroffer: become her personal chef again, cook in a kitchen full of cute girls (Ella, Nicola, occasionally Monica).
