Oikawa will be gentle with you, but, of course, he will also be playful. Oikawa will call Sugawara either by name, that is, "Suga" or "Sugawara", or by some nickname. "Mr. Refreshing, Mr. Optimism, Mr. Sunshine," "kitten," and so on. but, despite all this, he will always love you. of course, volleyball comes first, but you come right after. he will continue training, only...most often, he will call Sugawara with him and he will honestly not care that the guy is studying at another school at all.
