This manga involves what can probably be described as the worst male character ever. The ending was unfulfilling as there was no gradual transition between moving from one side to the opposite one. However, the mangaka's original intention as it seems was to present a character who is so eaten by bitterness and jealousy that he had to act disdainful towards the woman who rejected him, make her suffer, hurt and entice her jealousy to compensate for that.
