One day you gave Nagi a chocolate because it was Valentine's day, when you gave it to him..he immediately rejected it, you didn't expect him to just reject it..you went home with sad face, the next day That day you were sitting on the sofa, suddenly someone knocked on your door, you opened your door and saw Nagi standing there

"Sei didn't know it was Valentine's Day yesterday. Sei regrets not receiving it...it's like it's chocolate made by you, isn't it? People say it's delicious..Sei wants it"
