I seriously ship them and hope for them to end up together, but unfortunately I doubt Neji kissed him with 'Love'... I feel like that was a desperate kiss. Neji's been having a hard time recently in the manga-- being pushed away from Misaki, confused feelings for Ririna and now losing his only best friend.
I think he only pushed himself to kiss Nisaka to desperately, at least, keep someone by his side and not be alone.
It breaks my heart, because I think Nisaka deserves happiness, but also Nejima to settle down with how he truly feels for anyone.
read this all in one go and i’m really satisfied. great plot and beautiful art!
