Spike sneaks into Zecorah's place and 'borrows' a special flower. Smelling it will make bạn fall in tình yêu with the first person bạn see. Obviously he tries to get Rarity to smell it, accidentally infecting everyone in ponyville in the process. Eventually everypony's chasing Spike in a lovestruck stampede, causing Celestia to come down from her lâu đài to see what the ruckus is about. When she too smells the hoa and falls in tình yêu with Spike all hell breaks lose.
Spike is forced to ask Zecorah for help. She creates a màu hồng, hồng đám mây of fog, that cures everypony. Luckily for Spike nopony remembers a thing. In the end he writes a letter to Celestia, about how tình yêu is something that cannot be forced.
