Isao told Kotarou that he loves the Kotarou who loves (loved) Aiko. Isao also said that Aiko might have been his first love. These 2 reasons may have been why Isao is fond of Kotarou talking about Aiko. If Aiko did not come in to their lives they wouldnt have met probably. Kotarou wont be devoted father working in a daycare that he is now and Isao wont be the florist taking over the previous shop. She is like an idol to him. Another is like Isao was portrayed as the kind of person who is not affected by other things but just focusing on what is needed to be done or what's in front of him then do other things later. He is just focused on his shop and making Kotarou like hin that he did not have time to entertain jealousy. Even the time when his father was like trying to get he was firm on his decision not to go back back and ask his father to change his ways. Typically, other authors would make Isao cant refuse their father something like that. He also is good in setting aside his personal affairs in front of his customers. So ig what we are not seeing is that even if he got swooned by Kotarou and asks like a JK in love, he is a capable, focused, stern and confident person. I also think that a non bias Satou by his side and also warning him of "landmines" helped alot.
