I think, if I recall correctly (?) the novel mentions that Asher only has his hair up in public meetings, but in private or if he's not in "work mode", he has his hair down.
Let's hope he does, 'cuz he looks much more Aria's age if his hair is down. He looks like a sugar daddy with his hair brushed up. (Although technically speaking, Aria is older than him mentally, 'cuz she's already lived her life twice.)

Where he was smiling and waving to her with his hair down. I miss Asher having his hair down :'3 Not that he looks not handsome anymore but his hair down just suits him more, only my opinion though.
And yes, even though I read the novel already seeing it now webtoonized (lol) makes me still feel restless even though I know what will happen, the power of this. This will always be my favourite webtoon with that timetravel genre (づ ̄ ³ ̄)づ
