Body language

Okay, they both have issues, but one thing that really bothers me about the whole thing is that way Keiichii always allows whats-his-face to use possessive body language and never pushes the other away or mentions his relationship status. From the beginning, WHF grabs Keichii in exactly the same way Keichii grabs Shingo:

Then there is flirty touching and Keiichi doesn't step back and put his arm around Shingo. 5 seconds ago, Keiichi is all about the PDA, but WHF shows up and gets handsy, and now Keiichi isn't touching Shingo. Keiichi lets WHF get closer and Keiichi drops his hand from Shingo. Then Keiichi turns to the new guy and turns his back on Shingo:

Keichii doesn't say "This is my SO" or say anything special to Shingo to show they are a couple. Suddenly it's "Good work crewman!" and talk in a language Shingo can't understand. But what Shingo does understand is before this guy, Keiichi was all over Shingo. Now Keichii acts like Shingo is nothing and puts his arm around the new guy.

Later on their date, Keichii lets WHF put his arm around Keiichi and says nothing about being in a relationship. Keiichi may not be saying yes, but he isn't saying no either--and he isn't talking about how much he loves Shingo. For guy who is so keen to talk love in Shingo's world, Keiichi is closed-mouth around a guy coming on to him from his own social group.

"What are you doing?" This is a good time to say, "Texting my sweetie." But Keichii does not mention being in a relationship. And he lets the guy say things like this:

How is that okay?

And Keiichi allows the kiss without a word of protest. Afterwards, he has his arms crossed, but he still lets the other stand over him:

Why isn't Keiichi clearly saying no?

Just because Shingo is insecure doesn't mean Keiichi isn't being an asshat.
