Watari Wataru. Pink time of my school life a fraud (№ 381345)

The playmate, heh... I like that it is easy to understand. Clearly defines the environment.
This is clearly rather vague concept of "friends", so I really kind of liked.
The world is full of concepts that have no precise definition, but which is constantly used in conversation. Well, for example, it would be much clearer if instead of "wedding", "love", "romance" would say "they are looking for mutual benefits", or "they want your money," or "they want to look good in the eyes of society," or "they want kids" and so on. Although to say that they want someone for his money, it's really awful.
