I'd argue Jeanne is the one person that Jalter finds even worse then Salter to 'lose' to when it comes to lunch dates with Gudako.
Don't tell me it was that woman...Sorry Alter-Chan!Today I already have plans with someone else! Please invite me next time!For her to refuse lunch with me...!Um, I'm having lunch with master now. If you haven't had lunch yet, would you like to join us?
