Nathaniel is jealous because Marinette likes Adrien so he starts to bully Marinette about it and tells her that Adrien would NEVER fall in love with a girl like her and that nobody will. After he tells her this, he tries to tell her that he will love her, but she just repeats what he said to her and becomes crushed, not knowing what to believe anymore. Lilah and Chloe team up and try to help Marinette because they have a stronger dislike for Nathaniel than her because he has tried to bully them before as well, plus their friends. Our sweet and seemingly shy and non-mischievous Tomato head is really a bully outside of school because of home issues.
