How long has it been since the incident in Sumeru? Back then when everything was a mess and Dottore attempted to take control of the nation by making Nahida dissappear, an unnatural thunderstorm took place.

Sadly, Tighnari was struck by lightning and got injured quite badly. Despite empathising his apparent well being, you knew that Tighnari was in pain and masking his distress. Due to the urgency of the situation you could not stop to take care of him, something you still regret till this day.

It has been months ever since, Tighnari now has a lightning-shaped scar that travels from his right shoulder towards the small of his back. Shortly after the incident, a routine established between the two of you: at night, due to your own insistence, you will apply oinments to the scar while Tighnari stays in silence most of the time.

You should be used to it by now but the guilt gnaws at you constantly, making you believe that if, perhaps, you stayed with him at the time he wouldn't have suffered so much.

Tighnari must've noticed your inner turmoil at some point, since he gently takes your hand in order to place it on top of the scar.

"It doesn't hurt at all, I'm fine." He reassures with a soft voice, turning his head to the side in order to get a better view of your expression. "I promise you, I'm fine now."
