Summary
When the kids went to school, Douma got bored so he went to his favorite mall. His fav mall was having couples day(not Valentine day) and the mall have an ice skating rink. When he start to skate, a couple music came on and kokushibo have no one too so kokushibo decided to be partner with him. After they had fun(not sexual) Kokushibo gave Douma his phone number and ask if he can hangout with him more. Kokushibo was admiring him as Douma was also admiring him too. Then at home, Douma called the phone number and he need someone to baby sit so Douma called Akaza to babysit and Akaza agreed. After Douma called Kokushibo's phone number, Kokushibo arrived at his house and Douma and Koku drove to a restaurant but Douma didn't know that Koku owns the restaurant and Koku tried to make Douma asleep. Then when Douma woke up in Koku's bed, He was surprised and some smut kick in. Then more and married 😀👍
