My husband can't go home because of overtime, my brother-in-law is visiting on a business trip, a sudden power outage... As a result of a series of coincidences, I crossed the line with my brother-in-law. I'm lonely because my husband doesn't care, my brother-in-law who is divorced and experiencing loneliness ... I touched my hands in the dark and became conscious of each other. And impulsively kiss... I can't do this... even though I knew it wasn't good, I couldn't stop. Only during the power outage...only once...only tonight...while making excuses to myself, my brother-in-law hugged me for 'one night only'.
