I really enjoyed reading the adventures of this (fake) Otaku couple during the 2023 contest! They had a lot of ups and downs, and I just felt so at home seeing all their silly adventures. I won't spoil anything, but it was an entry I have no regrets reading!
I'd have to say my favourite parts was watching them navigate around their parents. I think all those interactions were handled very well.
To think, it all started with blackmail... XD
