I feel like it's extreme admiration and the story will probably keep it that way, but it's possible that there's some unhealthy romantic feelings bubbling deep beneath the surface, because to be that obsessed with your brother is just unnatural, especially as his jealousy and red eyes was set off just from seeing Arte smile at Eunwoo o.O
Is he in love with his brother (in a romantic and unhealthy way) or is just that he admire him too much?
