I don't know why, but I'm not a big fan of the childhood friends-turned-lovers routes. They usually strike me as anticlimactic. One friend confesses, and the friend either immediately says they feel the same way, or they think about it for a day and then decide they feel the same way.
I do like Hyper's sex scene in the beginning though.
'Doppelganger' is used frequently in America too, so it's okay.
Yeah, I've played all the way through WSSAP a few times so I know what happens to Cornelius. He's an angel, so it shouldn't be that easy to kill him.
Haha, well Alex and Janus clearly have an open relationship. That said, I don't think he's a cheater, just shady.
And yes, I've done the labyrinth a good 10 times now.
I actually love EA's lion, Darius. I even become a $3 Patron on the months he'll have an update. Since your character isn't actually dating him, he technically isn't cheating. That said, as soon as he realizes how much it bothers your character, he stops sleeping around. Even though he's sleazy at first, I still recommend giving his route a try. I don't want to give away a spoiler, but he does become oddly affectionate, to the point he's bothered by it himself (and it's obvious).
The lion in UB is Juleon, and I played that update yesterday. That lion is such a damn tease! I wanna yell at him to stop the game of cat and mouse already. My character's getting blue, I swear.
I do like UB a lot. Gear, Reiner, Juleon, and Grizz are my favorites, in that order.
Sonic's Alpha... That sounds like an Omegaverse title. I actually really love Omegaverse stories. Also when it comes to fanfiction I prefer more romantic than horror. However, unlike most Americans, I like there to be conflict in some places so it's a little realistic.
I'm a huge Riren fan (Levi and Eren from Attack on Titan) and my favorite ff (fanfic) is The Intern. It has a good amount of conflict, but such a heartwarming story.
We're actually seeing Brightburn for the second time today. My brother hasn't seen it yet.
It is similar to Superman, but I don't think it's bullying that pushes him over the edge. But I'll leave that up to you.
Also, his name isn't Clark Kent, so it's not Superman in an alternate universe.
I think your English is better than most Americans who write fanfics. Your English doesn't have to be perfect, so if you want to write then you should.
There's really not a lot of Killigan's Treasure. It's also being rewritten so it might be better to wait until the new demo is released. It's being worked on now (after the project was abandoned for about a year). Obviously it's your choice, and the demo isn't bad, it's just pretty short.
