Where is the BL/ yaoi for this

yes, in our imagination.

But if you hesitate to read it for that reason, I assure you that the bromance scenes in 1st volume are worth reading ლ(´ڡ`ლ) just don't go further than 1st volume and don't expect more. I wonder if the light novel from which this story is based from, about the two mc in the future, is BL or not, I can't find it anywhere.

Thanks All-deja-vu
