DeviDeviKawaii's question (2)

Please recommend me some series with two male leads that have this atmosphere but it's not romance like

Yabun ni Kyuuketsu Shitsureishimasu

I Want To Be Killed By Your Beautiful Self

An antagonist whose whole role is to just be evil so that the main character appears better.
Even worse when the main cast is interesting and well-written yet the conflict they have to deal with us so stupid.
