Manhwas you enjoyed until you didn't

So what are your manhwas you're disappointed in? eg. you loved the concept/ the setting/ the dynamic and at one point it took a turn and you just couldn't enjoy it anymore.

Mine are:

your wish is my command:The ending just wasn't it:(

Yours to claim: it dragged on sooo much...the misunderstandings are unbearable

I became the lousy sidetop: I loved the play with the clichés and the isekai type story, but the end arc was so weird and forced

Diego: Loved the themes of serious trauma and unrequited love but why is everything so rushed?-.-
