Although Reina confessed this to Kumiko, they didn't go out immediately. Kumiko had said she needed some time to think about it.
But eventually they started dating and it was awesome, Kumiko loved every day with Reina. She met her parents, who were really nice as well. Her parents loved Reina.
The first time they did 'it' was after almost seven months of dating and going out. Kumiko could never forget it.
The music band did good, gold had become something they were used to by now.
