Just my two cents. Now there are 8-9 chapters left. I think Yotsuba escapes from confession or says she doesn't return feelings. Fuutarou follows her and / or I think he does something to convince her, so will the other sisters too and eventually get married. I hope there is something about the evolution of the sisters and maybe a chapter on why the choice was made. Maybe there will be something for Itsuki and maybe also for Ichika because it seems to me that something is missing from them.
