It is seriously funny how much out reading lists over lap.

So I'll give you some info on a few of these. Some of these have official translations that forced the original translator to take it down, but you can still read them for free (or close to free) through the official translator app. Radish has "The Villainess is a Marionette" and "Untouchable Lady." It gives you a free chapter after a timer is up or if you watch an advertis**ent or something like that.

"Regina Rena – To the Unforgiven" is on Yonder. I think they give you a free chapter once a day.

You can also check out the spoiler threads for these novels. A lot of times there are fan translations or MTL chapters posted on there because any websites that try to post them get taken down by the Koren publishers. At first I avoided the spoiler threads because I don't actually want spoilers, but they usually have links or explanations on where to find novel raws or where to find the translations that can't be linked on NU.

"This Marriage Is Bound To Sink Anyway" also has an official translation. I don't know if you started that one before the translator removed it, but I was almost to the end when it was taken down. There is an official translation coming out slowly and a manhwa. The spoiler thread links to the raws so that you can mtl that one also. Spoiler threads are not linked in anywhere on the NU page, so you can only search for them on the forum. Here is a link to that one though.

"Failed To Abandon the Villain" is completely translated. They had to take it down, but you can find up to chapter 111 on aggregator sites that copied the site before it was removed. Chapter 112 and on are posted on a patreon account, but are available for free.
