I'm going to go back and re-read everything, and mine for hidden clues.
But as it is, I don't have any preference about who ends up with whom. Ei is a waste of space, and I don't wish him on either girl. Also, I think he is gay. Also, up until now, there hasn't really been any emotional depth before this chapter, so be it twin-tails, or Wolverine, both are "pleasant" enough, but neither has shown a particularly deep interest in Ei, and if either or, or both now show an interest in MC, I don't have any strong opinions on any of ot as yet. It is like un until the last couple of chapters, it was a totally different story, and I don't hate it. However, even if the MC is damaged goods due to previous trauma, is that really grounds for the girls to get interested in him? Will they feel romantic, or just feel like fixing him?
