Shikimori's Not Just a Cutie (2022) : 1x11

Shikimori-san is at the mall to buy an outfit for the first date she and Izumi-kun have had in a long time. For some reason, her older brother, who still treats her like a child, is at the mall with her. Her brother is actually quite shy around people he's never met, and before he knows it, he's surrounded by young women and unsure what to do. Shikimori-san takes him by the hand and leads him away, which reminds her of how she always used to be the one dragged around by her brother's hand.... and of the days when she didn't know what she wanted to do with her life.
