Hello.

1) I'm not sure which one of the two it was, but the story is focused on an immortal woman. There is some kind of tree that releases it's seeds or spores which can't usually be seen by humans. If it enters a woman she becomes immortal, if it enters a man he becomes some kind of angel. Immortal women can't go near the anger because they can't resist them and angels kill them. So they usually scream..then die. I also remember the main character (the woman) once got minced by an airplane's motor or whatever it is and lost her memory for a while.

2) Has a manga and anime adaptation. It's about a vampire woman (kinda) and the man she turned who keeps looking for her. It starts in the past, there's a man running away and he (with his servant) hides in the woman's house. He falls in love, she turns him, but they get caught in the forest and someone kills him before he is finished changing I think. Then goes a time skip and I think the man has trouble remembering what happened, I think he has flashbacks of some sort. That's as far as I remember for this one.

Any help is appreciated. Thank you :3

second is Kurozuka just finished reading it yersterday so i am pretty sure

first one sounds like Mnemosyne
