Twins who don't look like twins at all are infatuated
with each other. Third sister
and an exogamous suitor
cling for one of the twins each. You'd think something could come out of it. Whether it be good or bad, something could happen. Theoretically, every kind of fiction depicts some sort of action, some change in the reality which is narrated.
HA HA, WILLIE!
Nothing like that happens! Chapter 0...1... whatever, leaves the watcher with exactly the same though on the characters than the final one. Nothing has happened in between, the characters don't even seem to remember that theoretically the introduction of new people should make things change. NADA!
A combination of character dynamics set in stone, a lack of chemistry quite noticeable in the dub, and a Slice Of Life
"comedy" which doesn't show any meaningful part of their lives brings a very boring piece of crud which you should avoid. My time was sacrificed so that yours won't be. I'd like you to appreciate that gift.
