Nisekoi - Season 1 Episode 19 The Play

Due to Chitoge's refusal of accepting the role in their play, Kosaki steps in and takes the role as Juliet with Raku as Romeo. Whilst in the midst of rehearsals, Raku and Chitoge gets into a heated argument over their fake relationship. As Raku vehemently states how dysfunctional things are between them and is considering to end their ties, Chitoge slaps Raku out of indignation. On the day of their play, Kosaki gets injured after rescuing a fellow classmate from a fall. With no one else to take over Kosaki in her role as Juliet, Raku approaches Chitoge and convinces her to take the part. After Raku apologizes and admits he doesn't despise Chitoge as the latter had presumed, Chitoge leans unto Raku and accepts the role as his Juliet.
