Companions

On my fruitful journey, I've made two companions Razor and Sienne I met Sienne first and made her my lifetime friend Razor came second, unexpectedly so Sienne was a new feeling, filled with depth and emotion Far deeper than I could imagine Curious me I wanted to swim deeper and see what laid beneath Razor was slim but had sharpness in his demeanor He seemed set on what he wanted, a clean cut through the flesh of ambition Sienne was lovely to explore, a beautiful view beneath the surface though scary as you may drown Razor was intimidating, yet calm and perfected I may have dived too deep into Sienne, I feel a sense of struggle to grasp air at her sight I may have leaned in too far into Razor, his ambition and passion leak through the clean cut that's left on my flesh Which companion, if I may ask, should be my end?
