In the last chapter...
Watari warmly smiled, "Now, Ryuuzaki. You heard what I said, what's wrong?"
"I….I…um, Watari have you ever been in love?"
Watari solemnly sat next to the ace detective.
"Yes. I was once."
"With whom?"
"Ah, you wouldn't want to hear a story of such frivolous manner."
"No Watari please!!" pleaded Ryuuzaki, Watari was shocked, "I mean, please," said Ryuuzaki, staring at the Altar." I need to know."
Watari froze for a moment.
"Very well."
--
"Very Well. It all started over 50 years ago. I was a young man in my twenties, when I met the most beautiful girl my eyes had ever seen. Her name was Lana. She was gorgeous inside and out. She was smart and kind and had beautiful brown eyes. My love for her was so strong. And after only a couple months after meeting she was pregnant and scheduled to have a beautiful baby boy."
"Watari, you were married!?"
A tear rolled down Watari's cheek. "No, no I was not. Unfortunately, Lana and I were from different social classes. I was extremely privileged, a socialite of sorts. She was a farmer's daughter. Our world's refused to mesh. And once she got pregnant, it became worse. If anyone knew that I was the father my inheritance would be taken, my social statics gone. Lana wouldn't let that happen. She knew my life would be in ruins and she felt it to be all her fault. So instead, Lana took all the blame. She told her parents that she slept around and had her child in private. I don't go a day without thinking about her. I will always remember that when she lied about our child that day, I didn't stop her."
Ryuuzaki was shocked, "Watari…"
Watari suddenly stood up and started to walk out. And then, without even turning back Watari spoke.
"Ryuuzaki, do not make the same mistake I did, just because your lives are different doesn't change you're feelings for each other."
"But Watari, my love's family they—''
"Yagami-kun's family will understand, after all who wouldn't want an ace detective as their son in law?"
"WATARI YOU KNEW?!"
"How could I not, after all you always go for the preppy boys." Watari grinned, "It's not to late Ryuuzaki, Light doesn't leave for his honeymoon for another 5 hours, he should still be at the reception. Go to him."
Ryuuzaki slid off the pew and slumped over to Watari. They both stood there for a moment just staring at each other. Then, Ryuuzaki embraced Watari into a hug.
"Thank you." managed Ryuuzaki through tears, "I got to go!"
And with that, Ryuuzaki ran out the church.
Watari stood there for a moment, then reality sunk in, "Wait Ryuuzaki, you can't drive!"
