Primarchs are rather tricky to get a read on. Hmmm… Some will be bold and tell you straight off, but some would steal you and break your sanity just because they are not used to… this whole “crush” thing. Worse is a few would likely kill you…. Logically.

Unlogically? Some would be like grumblers but are rather sweet. Others are so happy to see you. It’s… kinda something that could be akined with the Yandere AU because they really don’t know how baselines things work despite being the sons of the Emperor of Mankind.
