His character is a workaholic to where, even when he's pulled into another world, he asks for a job and goes and does it as if nothing has changed from his previous job. The ML, Aresh, has developed some feelings for him as far as I've read, but it doesn't show just how much other than the rather forceful, (but necessary! There is no r*pe people! Trust me!) touches he gives to the MC. Their interactions are cute but weird (in my opinion) wherein MC treats ML like a pushy, mother-hen type, colleague and ML tries (and fails) to get the MC to acknowledge his feelings for him by baiting him with work and stuff, or at least that's what I'm getting from reading this. They're both first timers with the emotion 'love', 'like' and whatnot (meaning they've never bothered to think about it) and they're both headstrong in their own ways and very stubborn, so while it may be nice to know how they'll end up together (or not), it is honestly frustrating when the MC doesn't acknowledge it, sidesteps it and blatantly ignores it by focusing solely on his work. He has more connection to his Real puppy-like colleague, Norbert than the ML and it's honestly frustrating to read.

My prediction is that it will take the girl, Yua, the saintess from his world, to point out his "love" problem only until after she settles her own "love" problem with the prince crushing on her, which is still a long while yet.
