우산을 안 가지고 와서

One night when the hot tropical night lasted, it suddenly rained on Ji-young's way home. Ji-young dodging through the phone booth. Coincidentally or inevitably, it is in front of his ex-boyfriend Joo-hwan's house. Ji-young knocks on Joo-hwan's front door after much consideration under the pretext of not having an umbrella and encounters old memories there.
