Jin: "It looks like you misunderstood about Alex. We have no relationship similar to the one you're thinking about"
"That kind of love didnt blossom"
"He was like a parent, a sibling. It was a love similar to family"
Me: WHY THE FUCK YOU LYIN. WHY YOU ALWAYS LYIN?! HNNN OH MY GOD, STOP FUCKING LYIN!
Actually I believe jin more so that it came to light (though a bit late) that Alex has his own man, i just didn't like it that Alex was messing up their relationship and also lowering hamura's self esteem and making him waver and all that
One more thing, although kissing(with toungue) as greeting or whatever is unheard of in american culture but since this is fiction probably the author went with a different approach and made it out that its a culture in the plot.
I have to say, this is one of the most interesting BL stories ive read in a while. Im in suspense every chapter and im actually excited to see how this all plays out.
