I don't think he will ever find out unless he has your computer though. All your searches are for your personal views unless he has an access to your google account. IF he does, just clean your google search, go to the link to clean google search ( https://support.google.com/websearch/answer/465?source=gsearch&hl=en) after you clean it, change your google account password. Clean it first before you change the password. IF you lock mangago, that it basically blocking it, you will not be able to view the site unless you unblock it.
Why would you care of what people think of you? U know if eating shit is normal in this world then suddenly someone say that they dont like eating shit, that person will be labeled as "weird". Whats wrong with that? Whats your with people knowing the things you love? There are lots of "lowkey" fujoshi im sure of it but guess im not. All of my friends they know that i read yaoi and such and we are still friends lol but if we are not friends it means that they are not ur real friends yeah yeah blah blah blah i bet uve heard this many times. Just let me make this clear. Be proud of who you are and what you like. If you friend likes to collect rubber band and you dont then so be it. dahell can u do but to be their friend and support them.

I broke up with my ex 3 years ago but until now he still stalking all my social media. I blocked his all sosmed cuz he is really annoying. But I keep his Facebook, cuz he's my best friend back then. But recently he always comment my status with annoying words and embarrass me in public. So I decided to block his FB. I wonder what if he find out my Mangago account? He always tought me that I'm STRAIGHT girl. Will he give up on me? If he find out my weird fetish of Boys Love manga what if he tell to another friends?
