thank you, you saved me some bandwith!
It was a slanted opinion and some cherry-picked, inaccurate info. Ian is kind of an average every-man that you can push in any direction, since there are so many choices in the game. The only potential love interests so far he can lose to someone else without you actively trying to cockblock him - and which are only love interests if you choose to pursue them - are Alison and arguably Cindy. And you can avoid that easily enough by pursuing those two fully or just not being interested in them. Sure, there are a few shut-outs as it's not a Harem game. But it's hardly F-mc slanted and in many ways M-mc has the better playthrough.
If a Harem game or automatic, effortless, super-chad game is what you're looking for though, then yeah, it's not for you. You can definitely get Ian to super-stud state, but this is really a game of choices - way more than most AVNs out there.
