Tighlei

Tighlei is the friendship between Tighnari and Collei from the Genshin Impact fandom.

Canon
In the Sumeru Archon Quest, After Collei awakes the Traveler, She heads to bring more medicine for them, however accidentally drops the medicine. Tighnari notices her and reminds her she should be careful, stating he'll grab it for her after he's finished talking with someone else. Collei apologizes to him, addressing him as “master”. Once Tighnari is done talking with the person, he walks in where Collei and the traveler are, and Collei introduces him. Later, Tighnari requests for Collei to tell the others to stop bring their patrol logs, which Collei is confused at first, however does so after he explains.

Some time later, the traveler sees Collei and Tighnari talking, with Tighnari examining her hands as he tells her to be more careful. She says she will and asks about her next patrol, however Tighnari calls it too dangerous for her, causing Collei to believe she's useless. However, Tighnari tells her not to talk like that, saying she shouldn’t be worrying. After Tighnari sends Collei with the traveler to clean the statue of the seven and check the lights, the Traveler asks if Collei believes Tighnari is strict with her, however, Collei says they have the wrong idea of Tighnari, calling him kind hearted. Collei talks a bit more about Tighnari, mentioning at some point that she's always wanted to pet his ears. The next day, Tighnari claims he came to check on Collei, saying she's not well after the traveler asks. After they start asking questions, Tighnari suggests taking the conversation elsewhere as Collei is sleeping. After Tighnari is finished explaining her illness to the Traveler, he wishes for them to not let Collei experience emotional pain again.

Voicelines
Both, Collei and Tighnari share a voiceline about each other. In Tighnari's voiceline, “About Collei”, he says she was illiterate, however it wasn't a huge issue back then. He calls her a hard worker and a diligent student, saying she's made good progress. However, with her goal being to learn advanced medical techniques, she was still far from reaching it. He claims she puts too much pressure on herself sometimes, asking for the traveler to help her out sometime. As Collei's mentor, he says to consider it a favor for him.

In Collei's voiceline, “About Tighnari”, she claims despite Tighnari being stern and criticing, he has a gentle soul. She calls him patient when tutoring Collei, even reading out letters from Mondstadt for her.

Quotes
"When that child was first brought here, she was effectively illiterate. It wasn't a huge issue, though. She's a hard worker and a diligent student, so she's made good progress. Still, her goal is to learn advanced medical techniques, so she still has a long way to go. She sometimes puts too much pressure on herself... Help her out when you can, would you? Consider it a favor for me as her mentor. Thanks a lot."

"Although Master can be quite stern and is always criticizing adventurers for carelessly eating poisonous mushrooms, he is actually a gentle soul. He's so patient when he tutors me, and he even reads out letters from Mondstadt for me. I've always been very grateful to him."

Fanon
As of now, isn’t very popular, likely due to Sumeru just releasing. However, their interactions are positive, and they are shown to be good friends. Many people liken it to Collber. There were varied opinions on the ship at first due to Tighnari not having a confirmed age while some thought that Collei was still a teen, however it has been confirmed that Collei is actually an adult.

Most ship platonically, thought some prefer it as a romantic het ship. It is reflected in AO3, where it currently has only over 10+ works as a het ship, and over 100+ as a friendship.
