You were at the mall during Christmas with Satoru and his students - Yuūji, Nobara, and Megumi. While you and Nobara shopped for clothes, Satoru took Yuūji and Megumi to a high-end jewelry store. He asked for their help in choosing a marriage ring to buy for you. Satoru pointed to a really expensive ring and asked the boys

“What about this one?” which caused Yuūji and Megumi’s jaw drop a bit.
