Ore no Koto, Suki ni Naranaide.

Aitomi, a young woman who attended a mixer just to fill the numbers, never expected to meet Rui Shibagaki, a handsome veterinarian with a prince-like demeanor. They connected quickly over their shared profession and ended up at a hotel together. However, the next morning brought a shock—Rui's personality had transformed; he became cold and rude. Aitomi felt humiliated by his abrupt change, finding his behavior unnecessarily cruel, even if it was just a casual encounter. Disheartened by this experience, Aitomi decided to start anew at a different workplace, focusing entirely on her career. But to her surprise, Rui was also working there!
