where's the isekai tag in this? dude come from a somewhat fancy modern college classroom and is summoned by somebody (in this case the goddess, rusha) to this other world, that's how it mostly work right?
also, it the raw's source (comic walker), it's tagged additionally to this with harem, comedy, romance and reincarnation(?), and is targeted to seinen)
Ah yes how do you write a character that doesn't use his Isekai power to indulge in women? Make the women jump on you. You don't even have to suffer the burden of taking responsibility and in turn writing a responsible character. We are in peak dog water writing. The icing on the cake would if they are selling uncensored chapters behind a pay wall. 1star it is.
Also a normal moral world equivalent would be summoning a woman from another world to groom my balls. Make this into a Manga, sounds like an Isekai title ngl.
