Diluc and Lumine have been friends since they first met during their freshman year of Uni. Since then, they've spent a majority of their time together within their friend group, but they became even closer to each other when Diluc offered his shoulder to her at every turn for comfort when Lumine's brother passed. Unbeknownst to them, they both started developing a crush on one another yet never acted on their feelings, Diluc not wanting to put their friendship on the rocks and Lumine being inexperienced and too much of an introvert to be proactive. But when Diluc comes back from vacation, after having thought about her almost every day, he musters up the courage to finally confess. When they both take a trip to their hometown, Lumine is let in on a secret that threatens to derail her relationship with Diluc. Meanwhile, said man has his hands tied with finishing school, running his business from afar, dealing with his secretive brother, and keeping his girlfriend happy. Will Lumine be able to truly open her heart to what could potentially be true love? And will she be able to fix the aftermath that will surely come once that 'secret' is out? * i do not own genshin, its characters, or anything thats not the storyline* *this is probs gonna be a looong fic lol*
