Is this brand new couple having their very first fight after going official? Cute...
Wakana just isn't used to the level of attention Marin gets, I guess. Being a pretty model and cosplayer like that really desensitized her to the stares of strangers, while Wakana frets over people seeing him holding hands with his girlfriend.
Marin moving too fast for Wakana in one chapter was funny, but at least she's doing things in the "proper order" as they'd call it. It's called the "dam breaking", she held back on all these lovey-dovey things for so long, it all came out so quickly. He'll have to adjust soon to survive or be smothered by her love. Marin flubbing his name was so cute. Hope the coming anime season 2 reaches this part (including the ending, of course).
