Yes he fell in love, but he did not do anything to the kid when he is still a kid and he knows that it is not good too at that time. And fact that he only realise his feelings when he is dearing ln his presence when he is not around and put it in a book...
And college student in Japan are 18+ yrs old so it is good overall... ヾ(❀╹◡╹)ノ~
Bruh I don't think he love the seme when he is child in that way. Didn't u see he's lonely and writer. He been through day alone and one day one kid just appear and make his day bright and he love that kid not in that kind of love. Just normal love for kids. The kid make he happy and joy his day. Until the kid go ofc he feel sad bc the one who always with him not there anymore. Plus the one who wanna have sex with him first is the seme not the uke :/. The uke love the kid and still can't forget about how joyful his life back then that's why he kinda refuse to the seme. Bc he don't want it with him. He just love old day with him as a kid. The love he feeling before not love in that way pls put different between it. Don't be so narrow minded
It is not shotacon or pedo... And I even think thier relationship is natural lovers, jelousy, anxiousness and restraining urself for the sake of your partner... It is healthy enough for me ヾ(❀╹◡╹)ノ~
