Deep meaning is that the word "seeking beauty" first appeared in modern Japanese literature, which is another literary writing style opposite to naturalism literature: seeking beauty school. The original intention of being obsessed with the American school is to "oppose naturalism, which mainly exposes the ugly side of human nature, to find out the functional beauty, and to indulge in the pursuit of literary significance." In Japanese, Tambi is pronounced Tambi, which means "aestheticism and romanticism". For example, Tan Bi is romanticism. Indulge in beauty, indulge in beauty, and explain in detail that it is "the most flawless beauty that contains all good things and can impress people." Later, this word was used in BL (Boy's Love) comics by ACGN circles in Japan. Therefore, it is extended to refer to all beautiful men and the love feelings between men that do not involve reproduction. Finally, it developed into one of the synonyms of gay comics. Gentleman in the field of ACG, "gentleman" basically means "pervert", or more refers to senior pervert. Another extension is that "gentleman" refers to the metamorphosis limited to two elements. It can be considered as "abnormal thoughts and speeches", but "honest actions".
