On Cayenne's 17th birthday, Seiji booked a whole dessert café for her. It was at that time that that her three friends found out that he was actually rich. He knew that Cayenne likes sweets but she didn't get to eat much because she was poor. Therefore, he was planning to spoil his future wife.
He asked the café manager to design the whole café with pink-violet motif. He also bought a huge bouquet of tulip flowers. Cayenne didn't like accessories or jewelries but she likes to create memories with her friends. And instead of intimidating her with his riches, Seiji chose to make her birthday memorable by just simply eating out and giving her a small customized gift.
Seiji invited the whole class as well.
When Arthur found out what Seiji has prepared for Cayenne, he was really angry.
"Ha! You can do it right now but once I'm out of my mother's surveillance, I will make sure to keep up with Cayenne and make sure you won't be able to manipulate her."
