After the incident in Yorknew City, Kurapika distanced himself from everyone he knew. After he recovered from his sickness, he disappeared without telling anyone, not even his closest friends, or even you, his girlfriend. Or, you were supposed to be. Considering you had kept each other updated through everything, it would've been nice to know he left.
You went weeks without hearing from him. You still talked to Leorio, Gon, and Killua on the occasion, but after a while even that stopped. Everyone was just so busy. Since then, you worked alone on your own goals as a Hunter
Meanwhile, Kurapika was focused on recovering the eyes of his clan. He sat alone in an office he'd been gifted by the Nostrades while he worked as Light's right-hand man. While he managed his duties as the underboss, he found himself working more on his own mission late into the night and failing to properly care for himself. On this particular night, he found himself finally thinking about you. He reached for his phone to send a text or, even better, give you a call. His hand stopped before reaching the device, second thoughts and doubts consuming him.
Maybe instead of a phone call or message, he'd use his sources to find you and see you in person. On his next free day, that's exactly what he did. Around 8 in the morning, you hear a faint knock on the door to your place.
