[Athena]

If a group of people rent a house for a year,

and two people A and B have an agreement to occupy one room,
person A will live in during first semester,
and person B will live in it during second semester,
because both will be studying abroad in alternate semesters,

but person B does not sign the contract (the contract is only in person As name for that room)


but then person B backs out 6 weeks before second semester starts, because they will be staying abroad,


whose responsibility is the rent?


If there is no suitable subletter found, that the other housemates agree upon,

and the room will be empty for that semester that B was supposed to live there,

then whose responsibility is it to pay the rent for that room?


The contract is only legally in person As name, but in a verbal agreement, does person B still have the obligation to pay the rent?
