This is a manga fairly devoid of ‘normal’ romantic progression, but that’s not a bad thing whatsoever.
The fluff starts immediately and doesn’t end. That’s what’s so nice about it. The two are lovey-dovey and adorable from the start and if that’s all you want from this, then go ahead and read.
If not, this series will be monotonous and boring.
At least read the first chapter to see how cute these two are before you decide. Because I am definitely a fan.
