It's really, really annoying. She can be romantic, and it's cute. Like her want for kisses. but it pisses me off when she just ignores his feelings or just avoids it. It's only romantic when it's convenient for her and she has little care for his well-being. My man looks like he could be on the brink of clinical depression, and she'll go "chuu" and she thinks everything is magically better and that is enough. Shit doesn't work that way.
It's a fanatical relationship built on the author's ideals with little or no thought on the character and the realistic appeal for readers. i know they have their weird backstory to still get in. But relationships, especially marriage, do not work that way, and how they even ended up marrying (until they release the chapter in the future) will forever be a mystery to me.
It gets you to question if she is really interested in him, or interested in keeping him low key. What if her organisation is getting her to get him to stop being whatever he is against their organisation. He is the MC, so there is a very high possibility he is the best in the field, and they want to take him out with only one resort left. If so then maybe I can see the appeal. But they need to release more for this to be enjoyable.
All in all this is a mindless yap of my shitty, lack of knowledge in love and marriage opinion, take it with a grain of salt. (p.s. This is written at the time chapter 4 is out.)
