I believe both of these offer the perspectives of both male leads and if I also remember correctly these two had couples that were being SO stubborn about defining their relationship. The dreaded "we're just FRIENDS... (who have sex)". But overall very fun reads! They're also green flags, so no trigger warnings. There is a moment where a character says something STUPID in the meguro story, but the other character puts him in check right afterwards!
BLs where rhe couple basically share one brain cell
