where to read manga?

(i know i sound like a TOTAL loser for writing this but please help me out) 😭😭😭

I've been trying to read Alice in Borderland manga since last week. to do so you just search up "alice in borderland manga" and people say you just have to read it from the first site that pops up.

it starts really great; I get to read until 18+ and gambling ads kept popping up every time I finish reading one volume. there's also one time where I got redirected to an illegal gambling site. 💀💀💀 also to the point my phone ALMOST downloaded an unknown software. my phone could've got hacked lmao that was scary

is there any site or app where I can read manga without any of those??? i feel like most of the apps rarely have alice in borderland anywhere ://
