The end?

i dont understand Japanese but that looks like the end

Yes vol.4 is the final volume. So we have only 38 chapters and extra

Can you read the raws? I tried Google translate but it doesn't work. The last chapter looks like the MC does not choose both of them yet, but why extra is called ayase episode?

You can't read the RAWS Only preview of 1st chapter of each volume. So I also dunno what happens. Is there really gonna have 3P? I want her/him to choose only one!

(The link for the chapters preview I posted it here.)

Actually you can read raws before, you just have to be quick b4 they released the next update. And currently you can read the latest 2 chapters in https://www.urasunday.com/title/342/93705
So I know about the 3p. I think it was Valentine's day and the MC got drunk with the alcohol in the chocolate and attacked (straddle?) Mori, Ayase tried to stop her and the next scene we saw them all waking up in one bed. I don't know Japanese but it seems like they didn't do it, because they are acting normal.

I added that link on my post too.
About 3p. I know, but they added a question mark. It could be that they just end up sleeping after being drunk doing nothing else. Like a one-night stand that found himself with another in same bed but being so drunk that he couldn't remember what happened. But in the end nothing happened.
