Memories from Seoul — verses written in moments of longing

all that I know,
Memories from Seoul

all that I know,

of love

I know of no greater art form / than my lips brushing unto yours /

you're so easy
Memories from Seoul

you're so easy

to love

like a test I've prepared for / even though I have the answers / like an early morning bus ride
