Yes, you noticed in the other chapters as well of how he acts toward the brother too
RIGHT?!?, like he completely switches when around other people but soft on the hyung
Spoiler :
Rahman actually love Jaeui hence he hate Taeui cuz he's jealous of how strong their bond is, and they have their own side story ( though not mentioned directly in the original series)
I think rahman likes the hyung, cuz theres this one panel that while questioning the hyung his eyes looks so full of love, IDK GANG BUT THATS WHAT MY THEORY IS
