Why are Suzuka, Mihono and Falcon are drawn together so often? Is it because of the fanmanga of the 3 of them trying to date their trainers?

The three of them form their own idol group in an episode of Umayon, an official comedy spinoff. Ines Fujin and Maruzensky are later added to the group, but these three are the founding members.

All three are well known for focusing on a "front-running" strategy. Front runners are relatively uncommon compared to the more regular Pace Chaser/End Closer strategies, and these three are easily the most prominent front runners in the franchise. Smart Falcon and Silence Suzuka in particular are often paired together because Smart Falcon both in-game and IRL was often called "The Silence Suzuka of the Sand" due to having a running style that reminded people of Suzuka, but on dirt tracks instead of turf.

All three characters also have prominent roles in the plot of Umamusume's fourth scenario (and the current most recent one in the Global version). Concerts play a major role in the scenario's plot, and both Silence Suzuka and Mihono Bourbon initially see concerts as nothing more than pointless distractions to racing, but gradually find meaning to the practice over the course of the scenario. Smart Falcon, meanwhile, is the most concert-oriented character in the whole cast, one of the few who sees racing as a means to serve her idol career, rather than the other way around.
