there isn't any gendered pronouns towards mc, just some adjectives like "cute", "adorable" and "pretty" (which imo can be used for men too but alas) plus hinting at mc being (potentially sexually) harassed at work by their boss as well as describing the mc as really short or Leumin being extremely tall.. so, unless you are uncomfy with those descriptions, I think its pretty neutral in terms of gender (I played through all routes multiple times just to make sure there wasn't any gendered things to make this comment... though I may have missed something but I am certain I haven't)
