Meng and Lin are a couple who both work in film. They meet at an underpass on their way to a once-in-a-lifetime concert in Bangkok given by Utada. They took this very same route on their first date and so, on their way to the concert, they decide to roleplay their first date as memories of the years they spent together are evoked by sights and sounds. Midway through, those memories become tinged with sadness and a mysterious man appearing, bringing with him the feelings that have been disrupting their relationship.

This is an earnest meta love story set in an underpass where the journey of a cineliterate couple acts as a metaphor for filmmaking being like a toxic relationship.
