It's unusual to me for seeming love rivals to get along, but Haruki herself approached Minamo on her own. Maybe this is different from Kaido trying to get acquainted with Hayato. He's sizing up his rival, or getting a feel of what they think about the person they like, but I'm not sure Haruki was also doing that with Minamo.
I had hoped Kaido would light a fire under Hayato's ass when it comes to Haruki, but it seems like he's still as dense as ever. He does all these smooth moves on Haruki so easily, but it's a little annoying how he seems so dense when it comes to love. If there's a reason for it I'm sure I already forgot, however.
An unlikely meeting between Himeko and Minamo. So Haruki and Minamo are now friends, in addition to being love rivals. Although I am still uncomfortable about the fact that this is still technically a harem with Saki being the third girl interested in Hayato.
