Yup trapped in VR except its using peoples real bodies instead of character models with their real world fitness (at first, coma people ain't doing all that) and die in game die for real.
So like as close to a full isekai but reversible if they beat the game (100 level MMO), which the protagonist doesnt want to do but everyone else does because he is so edgy until he finds love and can have it in the "real world"

But its like 10,000 people get isekaid mentally at the same time. Second season is about going back in to get someone that didnt manage to come back the first time either.

There is a really really fantastic abridged series on YouTube by Something Witty Entertainment if you like crass but wholesome humor. Fixed a lot of the character flaws and terrible writing.
