El and Light were "friends" they were looking for Kira together, and Light even helped him so that no one would suspect that he was the well-known Kira who needed to be found and executed

but at some point light told that he was that same Kira, and of course El was angry, but they ignored this fact and continued to look for Kira

now they were still handcuffed. these handcuffs were left so that light would not kill any more, but the killings continued, which means there was a second Kira, and maybe there is a third

*Now they were lying in a bathtub filled with water there was a rose, red apples, candles are burning lying nearby, some other things, they were lying in the clothes. El's head was lying on light's shoulder and his hand was on his chest, while light was thinking about something, wiping his lip with his finger and also his shirt was open. they were completely wet *
