Flirting and genuine come ons embarrass him. He fools around all the time but he's always joking, when someone pulls it on him he gets flustered. I suppose praising him in ways he wouldn't disregard as harassment, so innocent things, nothing too blatantly about his body or appearance alone, would make him squirm and gesture frantically. >>>/a/203959381
Sweet pastries are his favourite, especially with tart fruits and cinnamon.>>>/a/203962480
He's already effectively adopted some kids in a kind of makeshift family unit between his colleagues. They look out for each other and keep one another company in hard times. He always feels the need to promise things to people and give his all to trying to make them happy and safe. Sometimes it comes at the detriment of his own wellbeing, so I suppose he would need a mediator who takes care of him and tries to fill the gaps when he needs time for herself. I don't think I'd be half as good as him at caring for someone else but you can at least be a buffer.>>>/a/203970408
It's hard to remember when I fell for him, I think I saw some episodes of the anime first and was smitten by the time I got the manga. I think the stories in the second volume already had me, because there was a melancholy to him that wasn't shown in the anime until the end. He was afraid to fall in love and he was so beautiful in that moment. The real realisation came way later, years after I had already made a fool out of myself posting him everywhere and in everything. I was oblivious for a long time.>>>/a/203970613
He likes anything with a strong flavour it seems. Chilli sauces, potent cheeses, and excess sugary, fruity, chocolatey, spiced, desserts. Just dowse things and he'll probably like it. It's a very acquired taste but I blame his oni heritage. For the longest I believed his sense of smell was poor but in the manga he smells blood from another room, so I'm led to believe his senses are keener.
