That's because it starts here:

;)
No this one is written later, it's explained here: http://www.mangago.me/read-manga/kare_no_shousou_to_koi_ni_tsuite/sa/c004/pg-28/. The chapter from Kare no... is a sequel. And they are a couple there, while here they are starting dating.
It seems there still should be a chapter with the goukon and Enami pretending to be sick before this one.
Its always good to read what the scanlators say!!

Oh! I thought it was a prequel cause they are talking about goukons and here it starts talking about them as well... You're right, I should have read it, too lazy, jeje. Thanks for the tip!!
Hahaah see what happens when you're lazy!! It's always good to read. You would be surprised at how much you really miss. Hence why people get so confused for their laziness!! But it happens:) You live and learn!
Is it just me or didn't this chapter feel like the first one at all? i felt like i missed something...
