ok I'm going to try n explain some of them bc I ship drarry n wolfstar:
I like drarry because there's definitely a duality to it. although in the earlier books, the two have a resentment towards each other, you can definitely tell there's a connection there. as shown by some scenes w his father, draco talks about harry a lot at home, and really makes a point to highlight his appearance, which definitely could stem from hatred but also something more. most of the evidence is found in book six, where harry spends many sleepless nights and a good portion of his time in general invested in malfoy. he claims it's due to suspicion, but no one suspicious goes as far as having visceral dreams about each other. also, it's clear that harry feels something positive for draco, as he saves his life in book seven. also in book seven, this feeling is reciprocated earlier, as draco helps harry escape from the malfoy manor, although he could have easily told his parents and death eaters that it was indeed harry. even in the face of such animosity and punishment, he still lies to protect harry.
lastly, wolfstar is pretty self-explanatory. the way sirius acts towards remus during their schooling years is so different from how he treats his best friend, james, and especially in their adult years, remus is so quick to accept sirius' innocence. they act like a married couple throughout the rest of the series, through remarks that can hardly be seen as something 'just friends' would say
sorry this was so long, just wanted to explain them more <33
