I'm secretly in love with my senior at work, completely captivated by his cool, gentle demeanor and handsome appearance. However, he cherishes me deeply, and when we're alone, his possessiveness emerges, revealing a dominant, sadistic side. Recently, he saw me being invited out for drinks by a coworker, and ever since, he's been holding me tighter and acting even more controlling. While I'm drawn to this side of him, I can't help but feel anxious about our relationship.
