Who was the girl, who squeezed young Jae Hoon's mouse ? Who did she become?
someone answered this down About the Mystery School Girl from Episode 8 [SPOILERS but not really anything to spoil]
Both Mouse and It's Okay to Not Be Okay are produced by TvN. Sometimes a Production House tend casts the same actor/actress for guest roles and support roles from a previous drama. If you haven't watched IOTNBO, then what I'm going to say is not a spoiler.
The female lead Ko Moon Young has a very cold personality. Ko Moon Young was especially cold as a child and hated butterflies so much that she would grab them and rip them apart. It almost looked psychopathic. This younger version of Ko Moon Young was played by the child actress Kim Soo In who is none other than this mystery girl from Mouse. IOTNBO was trending alot in 2019/2020 so the production house and/or casting director and/or script writers thought it would a fun little Easter Egg to place in Mouse where the younger Ko Moon Young meets our little serial killer.
Although the plot doesn't exactly match because the town/city of both the characters played by Kim Soo In are based in different locations, we can just make our own assumptions that she perhaps moved locations during her childhood.
So in the end, she wasn't really meant to be a mystery character who affected the plot. The character was an Easter Egg from IOTNBO.
