Arakawa Under the Bridge x Bridge

Synopsis

While cleaning his room, Kou finds a cassette player belonging to Nino containing messages for a supposed Venusian. When Nino spots this, she becomes angry at him and climbs on top of a telephone pole and refuses to come down. She eventually comes down when Kou offers to listen to the tapes, only to find Hoshi had recorded over them. As an apology, Kou makes a tape of his embarrassing secrets for Nino to listen to. Nino mentions that she was afraid of telling him her secrets in case she'd lose him.
