Tbh idk what to think of this manhwa.like I still didn't understand why colonel like chiyoung now
Probably close proximity mixed with the fact that he is bonded. Like as he acted nice it eventually turned into reality instead of acting. Pluse the bond made him instinctively crave chiyoung both physically and mentally and he could only deny it for so long before eventually actually falling for him. Also he only didn’t like Chiyoung just because he was a guy not because of his personality or anything so over time he saw more of his personality and feelings grew.
Hate the colonel all you want but comparing him to the other grape manhwa, he's 100% better than most of them. Although he's a douchebag
