When you see the relationship between the twins and Dowoon, I guess that you could say that Dowoon seems to be closer w/1 than 2. Sure, both of the twins are close w/ their father, but, like I said, Dowoon is a bit closer w/ Hana. It's kinda sad honestly..
In s.19, Dowoon would call Hana instead of Duri, every single time. Even 2 himself says that he always calls 1 instead of him. Why?? Maybe bc 1's older + mature, so Dowoon is sure enough to think that 1 will always pick up the phone every time he calls him?? Or bc he thinks that 2 wouldn't pick up?? Maybe bc he thinks that 2 is more capable to ignore his calls (since.. come on, we all know that he is), and knows that 1 is too nice to ignore his calls (not in a mean way)?? ldk, but, it bugs me, or l'm just overthinking too much.

Tho, maybe it's not how Dowoon treats the twins, but how each twin acts??
With context of the season, Duri does get annoyed abt Dowoon calling them, complaining that his father worries too much. It's ironic later that he says that Dowoon calls Hana first tho.
Also, Hana may be closer to Dowoon bc of similar interests. Both are into mechanics/robotics, but Hana is his son, so..
(There's a scene out there where when they take a photo, Hana is really close to his father. No jk, I just don't even remember if it was the OG or HoD)
Semo may be the most daddy's boy in Tobot, but I think that Hana seconds that.
