AAAAAAAAAHHHHHHH!!!
It's sad to see the other girls like that man.. Especially Nino & Miku...
It became quite apparent, if you look back. Why is Yotsuba not in her room during the start of her arc(the ending announcement) and Fuutarou with the lights shining at a direction, in-waiting, in Ch100..
Next chapter is probably going to be the explanation of choice. Looking at the comments, looks like Haruba-sensei has some serious convincing to do though.. Will there be a twist? Hmm...
Fuhh.. Anyways, luckily I came in prepared. I believe in Ichika. She's a strong girl. She'll get through this.. If there are indeed no twists.
PS: Doujin authors, please get your pen ready. There's already a Hentai version of harem ending, so a non-Hentai version please. Oh, and 4 other alternate endings too. XD
And people, be civil. Don't go harassing the author. Remind the others to not, too.
Edit: Just realized the juice. So, Ichika knew it all this time during the third day of the festival...
