The author seems to have gone through some hysteria while writing this but I refuse to think about what this can represent so here’s the thing ;
The title of this manhwa is ‘Adam’s rib’, a reference to that fact that in the bible, when god made eve (women), he took out one of Adam’s ribs. The ‘god’ in this that replaced mc’s rib with a pussy wanted him to understand how women felt by taking out a part of him and this was what lead to him having all these ‘experiences’
