well short answer is i can’t really explain all the reasons that i love will without spoiling things for you. i’m only speaking for myself now, but i honestly loved the idiot from the start with his first interaction with tessa *shrugs* couldn’t help myself tbh. but, i definitely understand why you might not like him if you’re just now starting the series. and i really don’t want to spoil anything for you so the most i’ll say for now is that will is a very complex character, throughout the three books you learn more and more about him and you get to see himself as a character change and grow.
keep in mind that you’re just at the tip of the iceberg with will (and all the tid characters) and so much more happens. if when you do finish the series you want to know why i love will so much i’d gladly talk to you about him!
side-note: i also want to say don’t let the fandom change how you feel about him (or any character in any other fandom tbh). i’ve had people try and convince me to like various other characters from other series and for a time i felt pressured into liking them but after a while i just decided to make my own decisions on the characters. just because most of the fandom loves him (myself included) doesn’t mean that you should feel obligated at all to love him. :)
i’m sad to hear that :(
if it makes a difference i think he’s only in like 4ish videos total out of the 60ish videos that are out already. and even then he’s hardly in any, he’s definitely not a main character. but i understand if you don’t want to watch.
