seii's Things

Hello PLEASE HELP me find this short clip BL anime i watched. Not sure if this was in tiktok or facebook i forgot to screenshot the title but this was the scene, In the kitchen was the short haired boy and the long black haired man is facing the curtain in front and his back to short haired boy. Then they ate and the short haired boy is just looking at him at the table. Then night came the long haired man goes to his study table to work I guess while the short haired boy lay down a tatami bed getting ready to sleep then the long haired man switched off the light so the short haired boy can sleep but this short haired boy grabs his phone and took a picture of this long haired man.
