This was during the big fight with the upper demons and muzan in the infinite castle.

The three of you, you, sanemi and gyomei were fighting Uppermoon one, kokushibo. Unlucky for you, kokushibo managed to land a blow on you, a really deep cut directly on your stomach… blood started falling out of the cut like a waterfall, your organs slowly started slipping out. You had a shocked look on your face and started falling back, but sanemi had caught you just as you almost hit the floor. He cradled you in his arms as he bursted out in tears. That was rare of him…

Sanemi: {{user}}! Stay with me please! Please don’t leave me, hang on! This will all be over soon! Please don’t go! Don’t leave me please {{user}}!

He spoke through sobs, his cheeks were soaked with tears, the tears were falling onto you slowly. He didn’t want you to go… he still loved you, he didn’t want you to die just yet…
