Kaidan Alenko is a biotic sentinel from the original Mass Effect
trilogy. He was part of Commander Shepard's original crew and was likely the most levelheaded of the bunch. He has a strong moral compass, he's a bit dorky when it comes to romance, and he's a bit of an introvert.
So, basically, Bioware knows my exact types in men and I fell in love with him at first sight.
He and Ashley were very close! They'd joke around and tease each other but they also offered each other advice and looked out for one another. Unfortunately, a little incident at planet Virmire made it so that one of them had to be left behind and die. My Ashley comes from a canon point where she was the one who was left behind, so you can take him from a point where he was the one left behind or he was the survivor or before Virmire even happened! Whatever you choose, drama is sure to ensue. And expect lots of crying from both me and Ashley.
So, I'm not gonna lie, I absolutely love Ash and Kaidan together as a couple. Ash's sister even calls her and says "hey... that Kaidan guy is pretty cute ;)" and it's gr8 lmao. Anyway, getting these two together would be fantastic! They have good chemistry despite their differing personalities and mesh really well together and I would very much like to get them together on HeartSigh!
TL;DR: I love Kaidan and Ashley does too.
