Japanese Light Novels Where the Male Lead Goes Abroad to Study

Looking for stories similar to In a World of Anime Crossovers, I Was Picked Up by an Angel from the Start. Please stop recommending youthful coming-of-age stories. I’m begging you, I really don’t like tsunderes. I really don’t enjoy reading about them. Recommend something with an angel like this, and please don’t add weird unrelated books. Japanese-style stories only.
