Curate, connect, and discover
I know most of the DBDA fandom probably thinks at paineland at the trope of "x fell first, xx fell harder" is Edwin falling first and Charles now falling harder; because Edwin was obviously shown first to express his feelings.
But consider this-
Charles falling in love with Edwin slowly a little more every day, falling a bit deeper for him every day they spent side by side.
And at some point later- Edwin is crushing hard. Realizing "oh shit, I love him-" and falling hard in a chaotic storm of feeling he doesn't know how to deal with, he's a complete mess.
Idk, I personally prefer the second version more but both options can be great interpretations of their dynamic.
