The story belong this fanart? Here we go:

The valentine came, sephiroth was all alone. he don't know what he should do in that day. kill people? nope, he didn't want to do it on that day. he thought about jenova and his newest plan. and... He met Aerith when she went out a shop with some chocolate.
Aerith: sephiroth!
Sephiroth: hah... i don't want to meet you today, girl! now, go... i don't want to kill people today... You are so lucky!
Sephiroth didn't really understand his feeling about Aerith. he didn't hate her, but... he remembered, at the frist time he met her, he felt so comfortable. She made he thought about him seft and his familly. She made he thought about his life. and when he knew that Aerith loved zack, he felt so crazy, he wanted to... kill Zack. He didn't want to kill her. When Aerith was together with Cloud, he really wanted to let her go with him. But the truth is... she will never...
Aerith: Don't want to kill....
Sephiroth: Yeah... Now go... before I chance my mind...
Aerith ran away. But after 1 minu, Sephiroth ran after her.
Sephiroth: hey! Wait!
Aerith: Uh? Didn't you say....
Sephiroth; i know what I said! how about a date? You and me?
Aerith: Uh? What? NO! >"< What do you want?
Sephiroth: today is valentine's day, isn't it? So we need a date for this day, right?
Aerith: But not with you! '_' I will have a date with Cloud! i bought some chocolate for him! Here they are... So let me go!
Sephiroth: i will eat your chocolate! You will go with me tonight or i will let you go with Cloud's death body!
Aerith: Y...you...
What could she say? She went with sephiroth and Sephiroth ate her chocolate. Aerith really felt so angry. She didn't smile in her date with Sephiroth althought Sephiroth didn't do anything make she sad at that time. Aerith felt sad, sephiroth couldn't feel happy. But what did he want? Kill her or make her sad? No... he wanted she go with him, together with him, love him and smile with him, to make he feel that he will not alone anymore... He felt cold in her heart, that what make him felt sad. At last, sephiroth brought Aerith to a place she had never gone to there before.
Aerith: where are we?
Sephiroth: A place i liked when i was a child. when i growed up, i didn't want to come back here. this place... the first time I kill people to complete my mission...
Aerith: Why are we here?
Sephiroth didn't say anything, he sat down and said:
hey! you must so tired! let's sleep!
Aerith: >///< WITH YOU? IN HERE? YOU ARE SO CRAZY!!!!
Sephiroth: Maybe...
And he hugged her. Aerith really don't want to be with sephiroth anymore. She lost her dream valentine's day with another man not Cloud. yes, she really felt tired. and she slept soon. But sephiroth didn't sleep, He looked at Aerith face and kissed on her hair when she couldn't feel anything. He sat next to her until the dawn. When Aerith got up, Sephiroth gone. And Aerith came back to the Inn, where Cloud and other people are waiting for her. She didn't tell anyone about her date with sephiroth.
"She can't fall in love with Cloud! she shouldn't and mustn't fall in love with Cloud"_ that was what sephiroth thought_" i will kill her... She must love me or I will kill her... I will not let her fall in love with Cloud just like with Zack before.."
And you really knew what he did with aerith.
He wanted to hold her, to make her love him and then... he killed her...
