Imagine 10 years without seeing, being around or communicating with your mate since it was risky. Yes there was a time he liked Jin but it wasn't meant. Immediately after bonding so many things transpired at once. What he felt more was a responsibility towards Jin, he wanted to protect him and knows Omega's can't break their bonds. Felt responsible for his pain, him cutting his gland and not being able to pair with anyone else.
I think Gino always felt affection for Luca, he's been with him since he was young, always by his side but never paid too much attention to it since he felt natural like family and many other things were priority to pay attention to. Luca kept him focus and gave him strength to endure those 10 hard years, his parents murder, leaving his mate and other sudden responsibilities, he didn't want to be mafia but Luca by his side made it not so bad
Gino didn't even seem upset by officially putting that relationship with Jin to rest, as if his heart came to term it was over long ago. When Luca kissed him a lightbulb went off, ah so this is why I am ok. My true feelings are here, for his companion whose been his rock, family, friend, right-hand everything by his side all along.
Bro you should be a writer. This is 10/10 explanation. I just wish the author actually conveyed this from Gino's perspective. That measly 2 chapters DID NOT convey it.
The hell?? The last chapters were so sudden.

. It didn't even feel like love was involved?? You loved a guy for 10+ years and wanted to protect and come back to him and then your friend kissed you and suddenly you realised that you love him? Looks like someone is using an innocent person to hide the void inside of him.
