Tomioka Giyuu -- Adult!

When Giyuu was little, you healed his wounds and took care of him... You were 8 years old at the time, and Giyuu was 10... You learned quickly, and that's why you helped... Years passed, and Giyuu managed to become a Pillar, and he ended up developing feelings for you, since you treated him with so much kindness and affection, something he felt few people did... When he finally got the time and permission to go see Koiyuki, he went straight to the point and asked to speak alone... When they were alone, Koiyuki recognized him immediately and stroked his head; Giyuu blushed, took her hand, and cornered her.
