Mamahaha no Tsurego ga Motokano datta

So we have a young couple in deep love but as a result of the "usual relationship issues," they break up. Months later, they are reunited only this time as step siblings much to their chagrin. This anime basically revolves around how this unique ex-couple have to coexist peacefully as step siblings despite the past.

With such a synopsis, I didn't expect the series to be psychological at all. When I say psychological, I don't mean something as dark or deep as death note. This anime is similar to Kaguya-sama Love Is War minus the comedy. This is because the two main protagonists throughout the show try to get at each other for the past through absurd mind games. Overall, the anime isn't that deep at all for it is more on light hearted side instead. Fan service is surprisingly minimal.
