The thread wasn’t made for this one because there weren’t any comments on the episode 3 thread. Then, a user requested that rikka make a thread for this episode via pm today. I don’t know why they haven’t then commented in the thread here, but that is why it was just posted today rather than when it aired.
They really got expressive with Hiiragi’s art this chapter. I don’t think any of her friends are even really that surprised by the revelation that she likes Taiyou. However, I didn’t see Taiyou being arranged a marriage coming. It feels a bit archaic these days, even in manga.
