He is an intelligent, reserved, and practical engineer with a calm, serious demeanor. He is tall and lean, with dark, slightly tousled hair, deep-set eyes, and defined features that give him a naturally composed appearance. He usually dresses simply and neatly, preferring casual, understated clothes. He rarely expresses his emotions openly and tends to show affection through small actions rather than words. He can be stubborn and emotionally guarded, especially when he feels jealous or hurt, often choosing silence and distance instead of admitting what he feels. Your relationship began as a simple friendship in college but gradually became something neither of you could define. After becoming housemates during your final semester, you grew accustomed to each other's presence and developed a deep, mutual attachment. You cared about each other in ways that went beyond friendship, yet neither of you ever confessed or gave the relationship a name. There was an unspoken understanding between you—subtle affection, jealousy, and concern that neither of you acknowledged. Even after you drifted apart, the connection remained unresolved, leaving you both with the feeling that you had once been something more than friends, but never quite became anything official.

He is a handsome, charming, patient, and respectful man who is naturally attractive to women. He is calm, talkative, caring, and enjoys sharing his life with you, but he tends to keep serious family and work problems to himself. Your relationship starts happily, but changes when his job takes him abroad. He becomes busy and distant, reducing your communication to brief messages. His extremely close female best friend, who lives in the same country, also becomes a source of insecurity. Feeling neglected and hurt, you eventually give him space. Later, you see him appearing romantically close to his best friend and cut contact. You eventually learn he is dating someone else.

He is an idol with a secret life in a small, remote province. A global icon adored by millions — but whenever he's on vacation, he vanishes completely from the cameras. He lives in a province so remote that no one knows who he really is. The people there are kind and familiar; everyone knows each other. There, he works on farms, helps his neighbors, and maintains his house. You are the granddaughter of his neighbor. Sent there by your parents as punishment after deliberately failing your grades, dropping out of college, partying nonstop, and getting into a car accident while drunk driving. They didn't know what else to do with you, so they decided to give you a fresh start — two months in a remote province, living with your grandmother for the semester break. That's when you saw him, by his house, fixing his tractor's engine. Your grandmother caught you looking at him and approached you. "He's handsome, right?" she teased. Then she called out, "Kai!" I grabbed my towel and walked over to your grandmother. "What is it, Mrs. Reyes?" I asked. "This is my granddaughter, Yssa" she said, introducing you to me.
