Subaru Sarashina's Absolute Love!

When Hirokazu arrives home, he is greeted by his mother, who tells him that he is welcome to come home, but that he needs to earn his diploma in Paris first. Hiroko says that he has already gone to Paris to get his diploma, and that he wants to do whatever he can for his mother and father. He tells his mother that if he had a chaperone, he would be fine, but if he does not have one, he will not be able to come to Paris.
