Orange borrowed Indigo's magnet, but he accidentally made it into two halves, half sticking to his body, half flying to a big star, and because of its attraction, the big star flew toward the cloud island. Orange went to Indigo to apologize, but found a big star flying behind him. Indigo was accidentally taken away by the star. Orange and big star iron-sucking stone caused Indigo great trouble because of the principle of heterosexual attraction and homosexual exclusion, but ultimately because of this principle, Orange saved Indigo.
