All out of love for Light!!" around in fandom and it's kind of amazing how much more this matches Misa's own perception as compared to what it actually is, in my opinion.Misa is definitely not in love with Light so much as obsessed with an idea of him. I really can't say I consider her "love" for him to be normal love, man.. Light loves no one but himself (he even considered killing his own sister 💀). He just saw Misa as a pawn, someone he can use for his own benefit and that's only because she had a Death Note and was toxically in love with him.
No. Light doesn't love anybody . . .but himself. He kills anyone who gets in his way, including his friends and family. Light knows that Misa loves him and used her as an asset because she had the.. You can also see by Light's reaction here that he knows L was being manipulative and fake throughout this exchange with Misa, so I wouldn't call much of anything about it sincere except Misa's excitement about helping Light and Light's disapproval over L's methods of solving the case.
