I don't even think I can call this BL, there is no love in this just BOY
probably later on, there will be real mutual love at least I hope
Actually, we saw two possible instances of early "crushes". The card Skyler gave to Yeonduk...and the poem Yeonduk wrote about Skyler as a kid in class. Skyler is Yeonduk's first love, and possibly vice versa.
