Luhan teaches Sehun how to respond to customers so they don't try to bite his head off, and Sehun teaches Luhan how to deal with pubescent teenagers and their strange (and more often than not, dangerous) antics. Basically just tons of OT12 crack. With a teaspoon of stupidity and Jongdae the shipper's antics added into the mix. Fun?  

Because there are 31 days in a long month, and 730 days and an ocean (full of tears) later, I still love you, even if it hurts. Basically Hunhan fluff and angst, and all of my feels summed up in a short 1K list.
