Today, It's My Turn to Pamper You, Onee-chan!
Kimi no Otoko no Ko
A little brother who's usually the one being spoiled decides to turn the tables and take care of his older sister after she comes home exhausted from a long day. He brings her water, gives her a shoulder massage, and pats her head—clumsy but earnest in his effort to cheer her up. A gentle, heartwarming voice work where he praises you with "you did so well today."
