If you ask Seiichi Yukimura what friends are, he will tell you with a smile: Friends are those who dominate the country together, watch movies and listen to concerts together, go to libraries and art galleries together, trust each other, abide by agreements, and most importantly, are always available when called!
If you ask Mr. Ikeda what a friend is, he will tell you with a smile: Friends?? They are girlfriends who share things with each other, pass notes and play with mobile phones during exams, take baths and watch action movies together, eat and make trouble, drink and sleep together, and most importantly, never betray!
More than friendship, lovers are not satisfied, you guess and I will refuse to admit it.
Let's see how two people with very different personalities can pierce through that layer of window paper!
