@George-Wang-a98vag7 said in Dahlia in Bloom Vol. 12 Discussion!:
Dahlia isn't plain, she just lacks distinguishing facial features or any awareness of the opposite sex so she thinks she's plain and nobody is attracted to her even though men were all over her including volf who tries not to be. I think everyone of her female friends tries to tell her. So the artist making her pretty now is accurate.
To be fair, the men who are all over her are that way because of her skill and talents as an inventor. She could look like a deformed goblin and it wouldn't matter. Volf, of course, sees the beauty of her soul, plus she's removing so much of the friction from his life from glasses to flying rings to heater packs not to mention the tasty food. Also, to quote The Sound of Music, “There's nothing more irresistible to a man than a woman who is in love with him.” 8-)
