What a waste of a lovely night
Touken has a love sence, a clear indication of romantic feelings(kanekis "I love her" and toukas I'm a fool for feeling happy that haise looked at me like that), shown mutual feelings, a wedding, a pregnancy and it all happened in canon. Drawn in the manga by the author. Feels good man. There's no doubt kaneki loves touka or that touka loves kaneki. There is no time skip "how did it happen?" Or "where does it show kanekis feelings?" It's all there in the manga.
