Maybe she actually meant sekaiichi lmao.It must be a typo xD
My guess is they shortened they long name of it.

As for the anime in eng subtitles,

It’s pretty cute, I rewatched it recently. Plus there’s a Valentine’s Day extra at the end with theee couples.
However, if you’re looking for the main media of kirishima and yokozawa, its a novel that September Scanlations have translated.
Uwaaa, thanks
Thanks for sharing the doujinshi. Kiri~Yoko couple is my favorite out of all pairings in Sekakoi. They are mature and equal ^^
