Liar liar hearts on fire

kokichi ouma,a boy who almost only spoke lies, he was somewhat arrogant and usually 'annoying '. The boy starts hiding his personality and getting colder. shuichi saihara notices his change of personality and wants to find out more about this sudden change. (This is gonna be like No murder school because idk how to do alot of tea i only have a medium amount of tea.) Ouma's sudden change of persona doesn't do good to his reputation...many found him and easy target to bully and tease. saihara wasn't liking what was happening and had to change things back to what they used to be.
