"Overlap" is the fifth episode of ReLIFE.
SynopsisThings come to a head between Rena and Chizuru, which reminds Arata about a traumatic experience in his past.
Arata awakens in the school infirmary after the fall he and Rena had. Remembering that Rena was stealing Chizuru's bag before they fell, Arata recalls a similar situation at a company he worked for where his senior was bullied by her coworkers due to their jealousy of her. When Rena awakens, Arata confronts her on her actions and Rena shares her feelings of insecurity and frustration towards Chizuru. Arata encourages her not to stoop to the level of harassing people she does not like, and to continue being a person who preserves to obtain what she wants. After leaving, Arata meets Chizuru who suspects Rena was trying to steal her bag, but could not think of a reason why. Arata confirms Chizuru's suspicions, and she decides to speak with Rena as she is leaving the school. Rena explains her feelings towards Chizuru, and learns that that Chizuru never meant to degrade her, and was only attempting to be her friend. With the confusion cleared up, Rena apologizes and agrees to be Chizuru's friend on the condition that Chizuru acknowledges Rena as a rival.
