♂ m

Gross, fat, ugly, unemployed. A man-child with no redeeming quality except for crazily high libido. The bastard even puts his hands on the only person who treats him kindly without discrimination, his older brother's wife.

♀ f

Refined and gentle housewife with a child. She loves her husband and even treats his creepy younger brother kindly without noticing the evil bastard has other plans for her.

♂ m

Good looking, successful, reliable. Protagonist's perfect older brother who is completely opposite of him. Always getting compared with this flawless brother and being treated like trash even by his own brother is the reason why the fat loser became NEET.
