How does feeling sad about feeling alone lead to joining a harem.
If anything wouldn't that lead to loneliness since your time with the "bf" would be limited by others, it's not like you'd magically grow close as family with all the girls joining one after the other.
Is it really that hard to just find a new bf that isn't a cheating, especially since she has an absurd E-manga body.
Though maybe having the E-manga body means she's trapped in an E-manga world meaning every guy other than MC is scum of the earth, but how would she know that, she's a transmigrator! My god, the plot thickens.
