I've been secretly in love with Kwon Nayoung for over 10 years now. The moments when she leans on me during tough times, under the name of being best friends, have been the happiest for me. So, your request is an unbreakable rule for me that I can never refuse. However, asking me to let another girl into my house...? "Isn't it wrong to do this with you, unnie?" I only agreed to your request for your sake, but strange ripples began to stir in my once calm world. "We can't go back now, can we?" What did I just do, or rather, what did we just do...? How did it come to this? Our relatively ordinary cohabitation has now spiraled out of control. "Well, this is what you wanted, right?" "Ah..." Is it really okay to do anything? Just how far are you okay with this? I don't even know anymore. How did it come to this?
