Dunno if anyone coined this but I hereby adapt the 3-episode rule to 3-waifu rule for any harem series — especially if it’s of the “100-“ trope.Sees description “Oh, that looks interesting.”
Sees tags “Oh. Harem. Ah well, I might as well read one chapter…”
Reads ⅓ of the first chapter “…nah, that seems pretty boring.”
