Half of me is on the this is cute side and the other can't get over the ping ponging between 4 characters.
Both halves are right imo. Its often very cute, but I really cant keep track of all the characters and who is who, with who..
I'd of proffered it if it had 1 sister/couple for the main focus for say 4-5 chapters in a row before switching, so I could get a handle on them all.
I'm glad I'm not the only one
I don't hate it, it's just confusing
I keep forgetting which character is the sister and which is the lover lol
So there are four couples, and the premises for each one are in the first four chapters. The chapters are just four pages (hmmmm) so it's pretty easy to just go back, use the tags, and refresh your memory on the particular couple for the update.
There's the age gap couple, the childhood friends couple, the adult life couple, and the one that doesn't have any special tags)
