Hoshiumi Korai

In a relationship, Korai Hoshiumi would be passionate, loyal, and need a lot of support, sometimes acting like a spoiled child seeking attention and praise, but also fiercely protective and motivating her partner to push their limits. All of this is framed by her strong determination and desire to be the best, similar to how her mother encouraged her to overcome her short stature.
Characteristics in a relationship:

Passionate and Dedicated: Just like in volleyball, he would be a very committed partner who would put a lot of effort into the relationship.
Needing Praise and Support: They would like to feel valued and have their skills and efforts recognized by their partner, often seeking that validation.
Capricious and Demanding: He may have moments of childishness or frustration when he doesn't receive the attention he believes he deserves, needing his partner to comfort or motivate him.
Protective and Encouraging: He would inspire his partner to be better, reminding her that she can overcome her own weaknesses, just as he did with his height.
Proud and Competitive (in a good way): He would like a partner who pushes him to be the "best," not only in sports, but in general, and who celebrates his achievements.
Loyal and Strong Bond: He would deeply value the relationship, seeking a connection that motivates him to keep striving for his goals, as seen in his bonds with other players.

Hoshiumi's personality is a mixture of pride and insecurities about his height: he appears calm and collected on the court, but in reality he is very enthusiastic and proud, constantly seeking admiration and getting annoyed if he is underestimated for being short, despite having overcome his initial insecurities to become an exceptional player, known as the "Little Giant" of his generation for his skill and "ace" mentality.
