Yes. Only Ai, more or less, fell into this category. Unfortunately, she wasn't that useful. I mean, she gave some EXP and even a bit of Qi, but nothing more.Yup, think people want a real true friend these dudes will leave you at one failure lol. Need a true friend who will always be down. Fan just seems Wu Heir potential as you said lol. I mean tbf he was one of the first to put faith into Wu Heir, but would not say friend or comrade. Just two people seeing a benefit in each other. If MC became useless he’d disappear.
Wasn't the benefit of her route to get stronger through copulation? Something like "one night equals a week of training", with the effect being even better for the MC. But for some reason, they only did it two or three times in months. What's the point of this? Like, even if there were no benefits, they still should have done it often, just look at the Thunderfaller example. At the very least, I think Nicky should have added an EXP bonus every week, "Additional EXP from relationship with Ai", or something like that.
