This got me into this pairing and reading the original series (the story really surprised me!)
Same, I always somehow read the doujins first before I look into the series they are derived from.
My favorite is when Andou dressed up so classy like it shook me. Also, when Oshida told her she’d want to be her real girlfriend than a fake one, I almost swooned. Lastly, when they married each other, that was beautiful.
