I wish I'm wrong, but I seriously don't see this romance going anywhere, the author will probably start milking more and more, like others do. The art is top-notch, but the fact that the author didn't make any progression in 90 chapters of the manga only shows that it doesn't matter, and seriously now... When I read a romance manga is about the romance, if I did care about other things, I would be reading other things. Those two been interacting with each other for a lot of time now, she loves him, and so what? Nothing? There's nothing really happening at this point, and Gojo seems in every chapter more and more like he doesn't care about Marin. This manga had such amazing potential, and will just be wasted like others, with zero character progression and no romance development till the bitter end, IF IT WILL HAVE ANY. Unfortunately, I started to have the same feeling as reading rent-a-girlfiriend at this point, and let's be real here... That's not something good to be feeling.
I don't get why those author's fetish with the confession being the ultimate goal... I would much rather read the 'after confession' then this sluggish and wasteful progression that lead to it (when it even leads to anywhere or have a confession). Not only that, but I want to see the couple interactions and how will they do it together, and how things will work... Anyway, it just feels bad.
