Just gave me the neutral feeling. Seungho is still the same and only changing a little bit. And that small change isn't exactly love like all the other yaoi romance. If the author is planning to make the both of them as like a "couple" or something it would take a lot of effort for Seungho to realize his feelings. Not just the "Nakyum fell of a cliff and Seungho saved him" but something else that would hit both of them REALLY hard in the brain but is seen as indifferent to others/seem small to others.
Why'd I write that...?
Don’t know either but I agree with what you said. Seungho’s feelings aren’t “love” yet. As I’ve said in other replies, Seungho has to redeem himself and author has a lot of work to do to make that happen
Yes, lots of mental and physical work to change a person who isn't used to the change sudden or slow they will notice and might be stubborn in going with the flow
When I first read chapter 35 I thought Seungho ruffled Nakyum's hair because he saw from afar how Inhun put his hand on top his beloved little painter's head when they were talking. I thought it was like "Let me try that too because you smiled when he did it and I want you to smile at me this time"
