Shows like Twice Upon a Time

Thirtysomething Vincent dreams of winning back his ex, Louise. Grief-stricken and driven to despair, he kisses the break-up goodbye by nocturnal parties and ephemeral affairs--until this day a delivery man gives him a parcel he has never ordered: a strange bottomless box, through which he experiences a time travel that would take him back to standing at Louise's side right before they split up.
