So I want to start this right off the bat. I am not one who celebrates Valentine's day. Never really enjoyed it, and probably never will. Not because of passed relationships with people, but simply because the idea of having a holiday to celebrate love just seems so business cordial. If that makes sense. Why celebrate love on a single day? Celebrate it everyday! And if you need a special day to really make it special. Why not his/ her birthday? Or better yet, be really romantic and make it a surprise, whatever it is. Love.
Now that that rant is out of the way, I have some anime choices for you all; if you feel inclined then go watch them. If you have already, go watch them... again. :D Most of the animes I'm going to post on this list deal more with the couples than the actual concept of "love".
1) Mirai Nikki
To start this list off let's go from dark to light. Haha... light. You'll come to know I don't do anything half hearted ;)
So yeah, Mirai Nikki (Future Diary) is the first one. A series about a middle school student, Amano Yukiteru, who is a bit of a loner. He has a friend though, who just so happens to be the god of causality, Deus Ex Machina. Deus offers him a phone that can predict the future, and thus the story begins. I'll try not spoiling it from here on.
During the series he meets Gasai Yuno. A mysterious pink haired girl who is practically super-human. As these two spend time together, it starts off very confusing to Yuki. He's uneasy around her because she openly admits to loving him. And like every male (me included), don't know how to answer that. But over time, he realises that Yuno truly does love him, and he begins to show her affection in return. This anime is dark, and really shows how far someone is willing to go for the one's they care about in a hyper-parody sort of way. For those men/ women who want a loyal, and I mean LOYAL waifu, Gasi Yuno is your girl :3
