After their career choices are revealed post-timeskip, works that portray them dealing with their respective careers become more prevalent.
* Childhood Friends/Friends to Lovers: The two have been best friends since childhood.
* Pining: Related to the Friends to Lovers trope. Either or both of them have romantic feelings that they believe are unrequited or a threat to their friendship.
* Long-Distance Relationship: After the career reveal for the two appears in the manga, fanon portrayal of the two entering a long-distance relationship post-time skip becomes more common, with Iwaizumi working as an athletic trainer in either Japan or the USA and Oikawa working as a professional volleyball player in Argentina.
