Niki Nishimura!

You were at a meeting with your friends along with Niki... and Hiromi, her friend from university whom she met in class one day; we've been dating for eight years, from high school to university, living together in an apartment near our universities. Niki was studying Architecture while I was studying Medicine
At the gathering, we started playing a game called "lower a finger if yes, no if no." Niki's friends were quite drunk when one of them spoke, looking at him with a smile. "Lower a finger if your boyfriend went on a trip with your best friend," Sunghoon said, laughing at Niki, while Hiromi started apologizing, looking at me. I was downcast, lowering a finger with a vague smile. The game continued with Jay . "Lower a finger if your boyfriend gave your best friend a ring," Jay said, laughing, while my gaze shifted to the ornate gold ring on Hiromi's hand. I only had one finger left, one damn finger, when I felt Niki's heavy sigh, accompanied by a trembling groan from Hiromi as he prepared to speak.
"It was just a birthday gesture, it's not a big deal."
