LynLumi

LynLumi is the het ship between Lyney and Lumine from the Genshin Impact fandom.

Chapter IV: Act I
Lyney and Lumine first meet in Fontaine, during Fontaine's archon quest. While the traveler and Paimon check on his twin sister Lynette, he appears and introduces himself as Lyney. Paimon then explains that Lynette was talking to them, which surprised Lyney as he is aware of her tendency to remain to herself. When Paimon asks about what Lynette had said, Lyney responds by explaining that there is a prophecy being spread around Fontaine. He then formally greets the pair by shaking hands with Lumine and patting Paimon on the back. After learning the reason for their visit, Lyney offers to take them to the Opera house but is interrupted by the Hydro Archon, who also welcomes the two unfamiliar travelers. Later, Lyney helps the travelers avoid arrest from the Hydro Archon Furina herself. The traveler then offers to help Lyney with the things he needs to take care of, so Lyney asks Lumine to give out magic pockets to the people of Fontaine, and also to collect flowers needed to make more along with Lyney. The job gets done fast, as so even Lyney compliments the traveler for really being fast and experienced. The two then notice a thief, and team up to catch them but fail to do so due to Lyney twisting his ankle.

The traveler and Lyney meet again in the Opera house for Lyney's and Lynette's magic show. But during one of Lyney's final tricks, an accident occurs, and while Lyney himself successfully gets out of his box, the other person doesn't, resulting a tragic death from being crushed leaving even Lyney shocked. Neuvillete then proceeds to stop the show and start an investigation, causing Furina, the God of Justice to press charges against Lyney and issuing a trial. As a sign of trust, Lumine offers to be Lyney's attorney.

During the trial, the scales are tilting in Furina's favor as she points out that there was a loud thud about the halfway point and expresses suspicion that he could not have heard it. She then exposes them as members from the House of Hearth, surprising even the Traveler and Paimon, as this meant that they we're with the Fatui. Paimon then asks why Lyney didn't tell them this earlier, as Neuvillete asks if these claims are true, Lyney looks at both Lumine and Paimon and says "I'm sorry." before responding that they are indeed true. The Traveler then requests for an adjournment so that he can talk with Lyney and Lynette. Neuvillete accepts. The four then enter a private area, where Lyney and Lynette immediately begin to apologize for hiding the truth. Once more, both travelers start questioning about the magic show, to which Lyney promises to not lie anymore, and explains his truth intention. Lumine eventually decides to believe in the facts and will keep defending Lyney & Lynette from the charges.

The traveler ends up winning the case, as the true accidental killer was found. Both Lumine and Paimon are ready to leave when Lyney and Lynette stop them, wanting to thank them for defending them in the trial, and also to apologize and explain themselves once again. Lyney ends up telling the travelers his and Lynette's past, and how the Knave saved them. Lumine apologizes, but ends up being unable to trust Lyney fully again, to which Lyney says that it's reasonable and that if the traveler ever needs help, he'll be there. Lumine understands this and says goodbye as she prepares to go, causing Paimon to hesitate before saying goodbye as well.

Fanon
Although the ship started receiving fanart and fanfiction already on the day Fontaine and Lyney got released, the ship seems to be not as popular as Lyneyther, the ship between Lyney and Aether. The main popularity of the both ships seems to come from Lyney's flirtatious personality.

There are currently 95+ written romantic works and 30+ written gen works on AO3.
