Yoshino was having a conversation with Tsubaki about how she's not even sure if Kirishima actually has romantic feelings for her or if he's just obsessed with her for the moment without really feeling attached to her because she wasn't too sure if he'd had any romantic experience before her. By the end of the chapter she comes to the conclusion, after finding out that Kirishima literally has no friends (lol) that he probably only looks at her like a guy friend and is confusing his platonic feelings for her for romantic "love" feelings.
Nao is Kirishima's ex-"girlfriend" (I'm putting it in parenthesis because we still haven't gotten Kirishima's side of it, knowing him she was just a fling during the time that she was still studying in Japan but we don't know for sure yet. We only got Nao's side of the story)

thank you for clearing it out for me.
but i am not really liking the character 'Nao', she gives uncomfortable vibe for me. also i think kirishima will fuck Nao again , because he looks like he isn't over her.
I don't want Yoshino to get involve with Kirishima any further than friends because now we have more reasons behind it ( he literally fucked her cousin so no no no) :3
i think kirishima had something with this Tsubaki girl in the past(there was a picture of having sex).Yoshino also knows something or suspected something maybe. And he is still interested in her or maybe something else. i didn't understand what they were saying.
Kirishima is really complicated. If he loved Yoshino, he wouldn't sleep around so much. He doesn't love yoshino, he is just interested in a new person, nothing else (personal opinion).
if he doesn't fix this sleeping around habit, its better this ship never sails. Yoshino deserves better than this.
but i think, this marriage will happens no matter what and kirishima will sleep around with yoshino giving zero fuck. Yoshino will never fall for this shit.
