It's easy to be put off by this just from the first chapter but if you keep reading you'll find that this manga has some heart despite how cliche it appears at first glance.
I first read this some millennia ago then came across it again here. Reading it the second time around it's still as funny and chaotic and waterworks-inducing. The scene where Hisui swears to the baby that, unlike his family, he won't abandon him, is the one scene I very vividly remember about this manga even several years later. To me it was as if he was giving himself a better childhood through this baby who was abandoned just like he was by promising to give the baby what he didn't have. Pretty sad and heart-rending stuff. I don't think it'll ever be marked as completed but tbh the story gets dragged on for longer than necessary after volume 1 so it's not like there's anything to feel bad about. To me they've basically gotten their happy ending. The main couple, I mean. Don't care much about teenage Haruhi.
Also, get yourself a man like Yu who loves honestly and earnestly but won't accept less than their due. The man's a saint among men for fighting his way through Hisui's layers of insecurities. That's how you know it's fiction lol
Really like the way the author depicted Chika's coming to terms with his feelings. It's a more authentic take than what you would usually see in other BL manga. I also love how Ryo doesn't take any bs and shoots down any of Chika's attempts to wriggle out of confronting their "situationship". He lets Chika know in no uncertain terms that he's serious about him, leaving him no room to doubt his intentions. I think that's a really mature (and healthy) way of "taking the lead" and is 1000x manlier than the typical trash seme that bulldozes their way into their love interest's life, bearing down on them until they give in.
I also really like the seme Ryo's mature character. It's refreshing to see this attractive and confident seme who's not afraid to be vulnerable when it matters. Despite knowing Chika's nature, he laid his feelings bare at great risk of getting his heart broken. We get to see him go through feelings of insecurity, frustration, and even hopelessness like a normal person would when they've put their cards on the table and let the other person have the upper hand. Showing a seme working through complicated feelings just as much as the uke really makes the romance much sweeter. This manga has surprisingly more depth than how it looks on the surface especially with its title being the way it is.
I'm excited to see what happens next. The only thing I'm really bothered by is that the younger bro got rapiered by a disgusting ugly old man. Truly a fate worse than death. ╥﹏╥
