One weekend, in the middle of the night, my best friend's girlfriend, who I'd had a crush on since we were students, suddenly showed up in my room... Apparently she'd had a fight with her boyfriend and had nowhere to go. I couldn't send her away in the cold, with only the clothes on her back... While I was listening to her complaints in the room, the atmosphere became strange, and I was captivated by her lightly dressed, revealing her overly vulnerable breasts, and I confessed that I'd always liked her... I took advantage of her broken heart and crossed the line, even though I felt guilty towards my best friend!
