This comment section is just full of stupidity. The kid is 16-17. His priority right now is school, and preparing for his future career path. If his passion is fashion, then it might very well be what he will be doing after he graduates. These girls are not gonna get isekai'ed and disappear forever. They, too, eventually will be busy with college, or whatever they want to do. They might not find him attractive anymore in the future, even. If he's not interested in romance as much as fashion right now, that's totally fine. He might not actually be that attracted to the pres. In any case, there's no need to rush. He's wise enough to be honest with his passion, and the pres could see that, too. Love and romance can be taken slowly.
Whenever he's ready to seriously date anyone, he would do so.
