Love Letters in the Sauce (完璧なラブレター Kanpeki na rabureta?) is the 89th chapter of the manga and the fifth chapter of the Ukyo Kuonji Intro Arc. Soun finds out about Ranma's new fiancé and chases Ranma around the house. Ukyo shows up to give Akane a note she wrote on Okonomiyaki inviting her on a date with Ryoga. Happosai bites off the part that has Ryoga's name, so Akane thinks it's a challenge letter from Ukyo rather than an invitation from Ryoga.
