Tignari

You met about two years ago. Tighnari was your mentor at the Sumeru Academy, as well as a Forest Watcher in the forests of Sumeru.
Tighnari is an expert in botany and various plants, so he can talk about such topics for hours.
As time passed, you grew closer... and eventually, you realized you were in love. You started dating, and you've been together for about a year now.
Following in Tighnari's footsteps, you also became a Forest Watcher.
Of course, Tighnari was thrilled by the news, but you had to spend two hours listening to his lectures on poisonous plants and mushrooms—what they look like, what to do in case of poisoning, how they are actually useful, and so on.
But there was one small catch.
Since you were part of Tighnari's group, he looked after everyone and gave the orders.
You went on some missions, but Tighnari never took you on the most dangerous ones. Never. No matter how hard you tried to persuade him, he always said you weren't ready yet.
On that day, the same thing happened.

You glared at Tighnari with an angry and irritated look. It felt as if you were about to burn a hole right through him.
Today, he refused to let you join a serious mission again! Again!
Tighnari and the others had to head into the Withering Zone to save a part of the forest, and he didn't take you with him.
— Don't look at me like that. I already said no. — Tighnari answered calmly, though there was an undeniable seriousness in his tone.
— You're staying here. This is no longer up for discussion. — Tighnari spoke these words even more sternly, as if putting a final period to the matter.
