Kodomo no Jikan (TV) EP12 - A Child's Time

The next day Rin doesn't come to school. Aoki notices this then he notices that Kuro and Mimi are getting texts from her. Reiji asks Rin what's wrong and she tells him she wants to go to school. He is still extremely angry at Aoki for "being alone with her". He also continues to have nightmares. Rin finds a letter in the mailbox from Aoki, and she later tells Reiji she is going outside for a while and he yells at her, thinking she is going to Aoki's house. He puts a padlock on the outside of her room to keep her from leaving. Reiji has some kind of breakdown when Rin threatens to stab him with scissors.
