The video is "the otome game world is a tough world for mobs", but the thumbnail is "the eight son - are you kidding me". Honestly, I don't know why they continue to use fake thumbnails. They do not prevent copyright strikes on RU-vid, so what's the point? They are just annoying.
My guess is someone told them to do that... Or they saw a youtube telling them to do that and like an idiot they are doing that.... That's my guess anyway.... And yes, when they stop being idiots and doing this kind of crap, I will stop calling them idiots.... 😮💨
The name of this anime is, "Trapped in a Dating Sim: The World of Otome Games Is Tough for Mobs a.k.a. Otomege Sekai wa Mob ni Kibishii Sekai desu Episodes 1-12 Japanese/Sub Version".
