Tbh i think their relationships gonna be purely physical or something, like yaguchi after getting rejected and is down in the dumps gets annoyed at tamuras pestering and fcks him until he can't speak, that or tamura quits his bitch ways and shows yacchan that he only wants him now and they get together like 2 years after or something yk.
Its been awhile since I read the previous chapters but I don’t think that was at all the reason yacchan developed feelings for toono and is pursuing him but rather during the time they were stranded yacchan expressed his own nature completely and toono had no problem w it, isn’t that the beginning of yacchan’s happy crush
their relationship is rooted in yacchans vindictive personality he barely knows anything of substance about toono and toono only liked him bc he thought he was cute they are the antithesis of toono and kashimas relationship bc their relationship has slowly been built and has had personal and tender moments so build it kashima has always been there for toono and he has relied on him and has sought out his attention and assistance not just bc he thinks hes cute but he values him as more than an acquaintance, they genuinely know each other and what they feel and think as well as what they’ve been through i am very passionate abt those two
Im passionate about yacchan and toono as well, you're speaking like kashima didnt like him at first because he was 'cute', Yacchan likes toono because he can act himself around him and toono still liked him. Telling us that toono just doesnt like yacchan for his looks and vice versa. The two of them have a nice relationship. I'm not big on kashima and toono because I personally believe its bland compared to yacchan and toono who have a funnier dynamic and also because it feels more natural compared to kashima and toono.
This isnt an attack you can like wtv u want I just personally prefer yacchan and toono.
yacchan being himself around toono does not prove that toono likes him for more than his looks it could just mean that he sees his looks and excuses his behavior idk where you be at where someones looks hasnt made someone see them with rose colored glasses and to your other point though kashima liked toono because he was attracted to him he translated that energy into investing time into toono and actually learning about him intimately and again yacchans reason for wanting to be with toono is getting back at yuu he is toonos acquaintance who hasnt put in the effort it takes to be a close friend let alone a partner

I dont think many of you even consider yacchan's feelings. Lets say he doesnt get with toono, I wouldnt want him to get with tamura, because he doesnt like him and showed 0 interest in him. (And i dont like the ship) So if he just RANDOMLY likes Tamura like how the author is doing with toono then thats a huge L in the story.
Yacchan x toono please happen... :<
