i agree with that to some extent. i think its because i signed up to read a specific story w a specific pairing, but then have another couple i didnt rlly care about thrust upon me.
a good personal example i can think of is 'heat & run,' the main cp had like 20 eps and then became a side pairing in their own story, i ended up dropping it.
ofc there are also exceptions where i end up enjoying the 2nd cp more (for me, its in 'fate makes no mistakes')
I've noticed that I'm not really the type for second couple stories. Whenever a second couple appears, I get bored and skip until the main pair returns.
I always wish that the author would just create a separate sequel with that couple instead of squeezing it into the main story (╯°Д °)╯╧╧
But there's an exception: Kashikomarimashita, Destiny! The only manga where I actually like the second couple much more!
Kudou and Miyauchi deserve everything ╥﹏╥
