One night, I had a drink with my senior at work, Angel. As the alcohol progresses and we start to have fun, Angel unexpectedly invites us, ``You're going to stay over, right?'' It's our first time staying at Angel's house...! The fact that I was invited to the house... an adult man and woman were alone in the house... Naturally, that's how it went... For the first time, I saw my senior's cute face right next to me! An angel you can never see at work
