After eating Mr. Handa very plain lunch, Panda gets Mr. Handa invited on a group date in hopes his lunches improves.  But when the 3rd male drops out, Panda goes to the café to find a replacement.
so wouldn't it be natural 
for him to ask me?
debería invitarme a mí, ¿verdad?
así que debió invitarme a mí, ¿no?
C’est à moi qu’il aurait dû
 proposer de venir, non ?
Se ele fosse convidar alguém,
 não devia me convidar?
