This is just my personal theory about their relationship:
At first yukari just was curious about Living!Yuyuko power, and approached her just to see how her life went, knowing that ultimately that power would drive L!Yuyuko to her death. After they met, yuyuko realized that her power didn't really affect Yukari and after a while she developed a dependence toward her (as she was the only living being that could spend time with her), on the mean time Yukari started to have feeling towards L!yuyuko.
Time passed and L!yuyuko ability got stronger, and with that her death was getting closer, and both knew that. As the power got stronger and tried to escape its vessel, L!yuyuko started to loose control over it. By this time they were deeply in love with each other, and yukari, as a desperate attempt to prolong L!yuyuko's life, tried to absorb the exceedents of the power that escaped L!yuyko's control.
This worked fro a while, but even for someone strong as yukari, L!yuyuko's power was a little to much and she started to get the effects of absorbing all those "deatly dancing butterflies" that escaped from yuyuko. This caused her to start needing prolonged sleep times in order to recover the damage caused by the butterflies, but she didint cared about that, the only thing really important was L!yuyuko's life.
Winter came and ultimately yuyuko realized how much Yukari was suffering just to try to save her life and she knew that while for now she was able to control the butterflies, her power would grow to much powerfull for yukari to take it. The met a couple more of times and both tried to act as if nothing was happening, but they both knew that it wasn't right. Yukari then tried to absorb some of L!yuyuko power (and tried hide the pain) but was unable to do much. "Im sorry Yuyuko, but I need to sleep for today, I will come tomorrow well rested"
At the next day, when yukari goes to visit yuyuko, she sees her laying on the snow under the cherry three, with the kimono soaked in blood and a peaceful smile in her face "Thanks for all yukari, I wont forgive myself if this power keeps taking the persons I love from me"
Yukari ended sleeping trough all that winter, in part to recover from the damage caused by the butterflies and in part to evade the reality of the death of the person she loved. After that yukari still had to take long sleeps to maintain herself, as the damge was so profund ot be healed by normal means, and she ended hating winter, as the image of the blood soaked yuyuko over the snow was imprinted on her mind, so she hibernated all winter from there and on.
After that insert the cannon story. Sorry if I made any mistakes as english isn't my native language and sorry for making this look like a fan fic xD
At first I thought this was a pretty typical Yukari/dying!Yuyuko picture, but then I noticed A) Yuyuko's already in her "ghost" form here and B) Yukari seems to be fading away.
That's my theory as well, that winter reminded Yukari of the time Yuyuko died, hence why she sleeps all winter long.
Goddamn it, I just want ONE sweet YukaYuyu 'fic. Just ONE! Is that too much too ask? Huh, Touhou fandom? Is one stinking YukaYuyu fanfic where Yuyuko remembers her past life, or something of that nature, too much to ask?

The first one is where Yuyuko found out about the corpse that Yukari has been trying to hide. The second one is that winter you're talking about. They tried to make Yukari wake up during winter for a "special" occasion.
