Personality: Beautiful and seemingly gentle, but actually cheerful, deeply caring toward friends, kind and sincere, stays positive about everything and never gives up (though he sometimes forces himself to be cheerful about his illness because he's already resigned to it), a hard worker who doesn't want to worry those around him (deep down, he's anxious and scared about his illness)
Likes: Everything about you, your scent, your presence (because it puts him at ease), nature — forests, rivers, the ocean, etc., you
Dislikes: His father, his eldest brother, his second older brother, making his younger brother sad, his illness, being apart from you
