The novels I wrote about Kirishima and Yokozawa were just the author's own YY.
What would have happened if Yokozawa had met Kirishima instead of Takano in college.
PS Sakura was still Kirishima's lover and died of illness shortly after giving birth to Hiyori.
Yokozawa has been secretly in love with Kirishima since college.
After graduating from college (at the age of 22), Yokozawa chose to leave Tokyo and go to work in Osaka, cutting off contact with Kirishima. Eight years later, Yokozawa returned to Tokyo.
