Meisa, my best friend's girlfriend, was a good friend of mine in my school days and we used to drink all night in my room together. After graduating, we had become estranged, but one night, my best friend contacted me and said that Meisa had missed the last train at a drinking party and was in trouble, so he asked me to let him stay over... The more she got drunk, the more vulnerable she was when we met again after a long time... Even though I had no ulterior motives as my best friend's girlfriend... I pretended to be calm so that she wouldn't notice my wavering feelings, but I let my momentum get the better of me and crossed the line! [Thanks to you, KMP is celebrating its 20th anniversary! ]
