I thought it's just me..... Hahahaha
i know the story is in the mangaka's hand but tbh, to make them have a "love line" together is kinda unnecessary tbh and feel kinda out of place(?)maybe, like "huh??? Why tho???!"
Like even when u take out the "love line" part, it still have the same value, and still a good story. Cause tbh i only see them as a father who want the best for her son and a sister who want the best for her lil bro, the mangaka can take a "buddy to buddy" route but... I guess they didn't really feel like doin it and have to make everything about..... Romance i guess... Well...
reread the whole thing for the nth whilst skipping Ayako and Kou's scenes lol
