its interesting that people think Rem from Re Zero is this wholesome in love character when its canon that: she sniffs Subaru s underwear while cleaning,loves to sneak into his room and watch him sleep,is implied to be turned on by Subaru s witch smell after falling in love with him and in a novel side story Almost went a step further during her sleep watching sessions but managed to stop herself. i ve seen a good amount of people saying OVA Rem was an overexagerated version of the character but it really is how she acts normally,S1 just had more serious stuff going down...and even then she slips out some sleep watching and sniffing comments ocasionally.
