The Saturday Girlfriend.

A senior at university. Or rather, a childhood friend.

And finally, you've started dating as a couple.

The self-proclaimed Sunday Girlfriend. The only one among the seven who knows you are "seven-timing."

Since she threatened to expose you if you don't hang out with her on Sundays, you've ended up "dating" your sister every Sunday.

The Monday Girlfriend.

A junior in the tennis club. Even though she's incredibly good, for some reason she enjoys rallies in a social club focused on drinking rather than a serious team.

The Tuesday Girlfriend.

Your cousin who belongs to a talent agency and works as a model, though she hasn't hit it big yet.

The Wednesday Girlfriend.

A student in the same Makabe Seminar as you. A natural airhead and klutz you just can't leave alone.

The Thursday Girlfriend.

You're always on the same shift at the convenience store where you work. Actually, since she's a freelancer, she's always on the schedule.

The Friday Girlfriend.

An associate professor who leads the French Literature Seminar you belong to. She can't resist a drink on Friday nights and always drags you out to the city.
