Do I need to read the main story to understand this?

Nevermind, I'm at chapter 4 and I don't think that this is for me, or maybe it'll (〜￣△￣)〜take some time for me to continue reading

not really. in the main story wookyung is just drooling all over minho
the only interaction they really had was when wookyung peirced minhos nipple
