I have a lot of thoughts about this manga but i can't express my thoughts very well but for me
-kirishima makes the story interesting. sometimes i like him sometimes i hate him.
-he made yoshino look more badass
-shouma is a better person than kirishima but kirishima looks after yoshino better ex: on daily basis, yoshino is the one taking care of shouma most of the time whereas kirishima could notice yoshino's habits (ch 11.6 pg 15) and does these little things to help her. He knows what to do on emergency situations like when she has a cold or looking after the warranty of the hair dryer when it was broken. Maybe shouma could also do that but the way kirishima could observe every little thing is both creepy and amazing at the same time.
-Shouma helps yoshino with fights and all but then he also lacks that area compared to kirishima. Isn't that why they let yoshino be close to kirishima so that he could protect her in the future?
-i don't trust kirishima's love. i knew that he's gonna fuck round but it still disgusted me how he casually proclaims his love then have sex with other (plus treat them also like lover) for information or whatever. he might get bored of yoshino in the future although he says he won't.
-im not rlly shipping yoshino and kirishima (bc he's fucked up on many ways sooo glad yoshino can handle him) but i like their dynamics better.
