One main theme is likely the idea of revenge itself. The protagonist is probably seeking to get back at someone or something from their youth.
Revenge is the obvious one. The title itself gives it away. There's also power and how it can corrupt or be used for good. Another theme could be friendship or loyalty as the characters navigate their dangerous world.
Another option might be 'Sword Art Online'. While not exactly the same, it has a protagonist who has to overcome various obstacles and enemies, much like in a revenge - themed story. In the world of SAO, the main character battles against the system and other players at times, which can be seen as a form of revenge against those who wrong him.
Betrayal is a very common theme. Usually, the main character has been wronged by someone they trusted, like a friend or a colleague. This betrayal then fuels their desire for revenge.
One common theme is redemption. The hero often not only seeks revenge but also to redeem themselves in some way, like proving their worth after being wronged. For example, in 'The Rising of the Shield Hero', the hero has to redeem his name in addition to getting revenge.
Since I don't have the exact 'my youth romantic comedy light novel' in front of me, it's hard to say for sure. However, in similar light novels, the main characters often include a group of friends. There might be a guy who seems cynical on the outside but has a good heart deep down. And a girl who is initially cold towards him but gradually warms up as they interact more. There could also be other friends who play important roles in the story, like providing comedic relief or acting as a voice of reason.
There's no clear indication that the 'My youth is annoying light novel' is popular. It could be that it has a small but dedicated fan base.

One main theme is probably power dynamics in relationships. Since the wife is a CEO, there's a lot to explore about how power is balanced in their marriage.
Well, the main themes include transformation. The character starts as a villainess but gradually changes into someone different. There's also the theme of power dynamics.
