It’s lovely that people can see something between others, and the thing is there’s the evidence to back in up for Yu and Mika. They have the best chemistry out of anyone in the series with how they think of, and treat one another.

On a case by case basis Krul can worry about her brother, but not be romantically involved with him, Mika can worry about Yu and be romantically attracted to him. Being worried about someone doesn't mean you like them romantically, just means you care about them as family, partner, friend, whatever it is, depending on who it is.

Yu does try and bring Mika into the squad, the same as Mika brought Yu into the orphanage, to give him a family and heal after enduring some awful hardships. Mika has been and remains the special one in Yu’s mind, fingers to his lips, their interactions, it’s something the manga goes to such lengths to display it all.

There are many reasons people like the series and as with anything they may have their own favourite aspects. This thread simply notes everyone’s views on why Mika loves Yu, romantic or not it’s precious and a prominent feature of a shounen series that focuses on action, everyone and everything betraying one another, horrible assaults and demons, vampires, seraphs, humans too, running amok.

With Mika and Yu, they have one particularly bright light that prevails over all the bad things that are happening to them in the story.
