Been a little bit since I popped into one of these threads. I haven't read the LNs of these, but here are some impressions of some of these series (in case I haven't mentioned them in the past):

• An Introvert’s Hookup Hiccups: This Gyaru Is Head Over Heels for Me! - (I read the manga adaptation) - I ended up dropping this one because it was just really dull. The initial setup never really gives any kind of payoff. Instead, it is just two people that are both "pretending" to be in a relationship while super-duper being in a relationship.
• If the Villainess and Villain Met and Fell in Love - (I am reading the manga adaptation) - This one has been interesting enough to keep my interest. It is a bit of a mashup of the Villainess genre (there is a broken off engagement with a jerk of a prince) and a weakest skill is actually the strongest (turns out her nameless contracted spirit is actually super powerful). It is pretty predictable, but it has been enough to keep me reading so far.
• Fired? But I Maintain All the Software! - (I read what is available of the manga) - This is a power fantasy for the software developers out there. It's basically an exiled from the hero's party adapted to the modern workplace. The MC is fired by a jerk boss, only for all the software she built/maintained to fall apart after she left. Meanwhile she is off living her best life in a new job (including lots of cosplay).
• The Fearsome Witch Teaches in Another World - (I read the manga) - I enjoyed what I read of this series but the TLs stopped (IIRC). Basically a teacher from Earth is isekai'ed and ends up as a magic teacher in this new fantasy world. Oh, also, she is super OP, because of course she is.
