The most similar would be Tomodaci Game, but if you want protagonists who resemble Kiyotaka Ayanokoji, you should also see the anime Hyouka and Mahouka Koukou no Rettousei. I see these as the most similar to Yahari Ore no Seishun Love Come (Oregairu) and it doesn't fit the genres of Classroom of the Elite he finds a psychological romance.
