I think she was happy, even though she didn't look like it. I think it's a bittersweet feeling for her... I really wish that Lala and Tor was able to be happy. Both of them had their moment when Lala was pregnant, and he scooped her of the floor and put her gently on the bed. I think that was the most romantic thing he ever done for her... I always wonder why couldn't he say he loved her dearly, and in the end he just went to her room, after she died, to reminiscing...
And i really hope that he could accept or at least meet her (Lila) in the next volume (volume 32). She is the spitting image of her mother, with curly hair...
