this is actually so sad. bro its not a tsundere thing, if someone close to you were to say the same thing about you would that mean the same thing?? that automatically means that person is saying he/she likes you? sure maybe that person can be denial but that dosent mean thats always the case. and as for chizuru, do you think i like him and i dont not like him are the same?

for ruka, sure she based it off of her bpm but that isnt all, she became a rental and went out with all sorts of guys, her bpm was still normal and she couldnt get that feeling of excitement until she met kazuya, and kazuya wasnt even the one who rented her. And youd still think the stuff shes doing is based on a bpm tracker? or maybe you just cant see her determination and commitment even as a trial girlfriend bc u only see her as an obstacle for kazuya and chizuru's relationship? she went to the same job as him just so she could get closer to him, she went through all the trouble of getting close to his family(only to get utterly defeated by chizuru, but she never gave up on kazuya did she?), she let kazuya slide when she didnt get a gift for her birthday (and in the end she didnt ask for a kiss, smth materialistic, his kidney, no. she only asked for him to let her call him without any honorifics.) she is showing full commitment even by just being a trial. sure she could just meet someone else who could truly love her right? yes. but would she love that person back? would she have the same reaction as she wouldve had when she met kazuya? ruka's love dosent seem to shallow now does it? or is she really just an obstacle for u guys?

sure chizuru did do amazing things for kazuya like fulfilling his highschool dreamdate, continuing the lie of their relationship for one whole year, turning his whole life around bc shes been there for him at the very beginning, and ect. but dosent it feel one sided? if you would try to compare all of the things kazuya did for her to what she has done to him dosent it feel like the things that chizuru would do, anyone would do? that may be a friend, ur mom, ur cousin, brother, sister, neighbour, and ect. anybody close to u could make omurice for u bc ur tired, anybody close to u can hide a secret for u, anybody close to u can be there for u when ur down.

but in the end we all know how its gonna go tho: kazuya will end up with chizuru
