No sympathy for Ikumi.

Tf? Ikumi is the victim in all this mess! Chiharu has been by his side like a pimp on his top hoe, he doesn't love him, he just wants to fk him until he gets pregnant. Meanwhile Ikumi over here is STILL trying to deal with the psychology of being a pregman who looks like a normal guy...he is not girly like the other ones and his childhood friend is determined to breed him; he's been grooming his body to be more sensitive. Each chapter dude is biding his time til Ikumi's next heat.
Has Chiharu asked Ikumi out on a date? Nope. Does he have a plan for if Ikumi gets pregnant? No. And aren't they 15? Does he know how much his family will be pissed if he does get Ikumi pregnant? Yes. and this chapter drives home how much of an ass Chiharu is.

Say

Ikumi is hardly a victim. In the 80+ chapters in this story, Ikumi is victimized probably 3 to 4 times. The rest of it is just him dealing with his insecurities of being a pregman and his tsundere relationship with Chiharu. Everything else are things that are happening around him.

Chiharu's loved Ikumi since they were little kids, before knowing he was a pregman. That's a matter of storyline. By not having sex with Ikumi unless he was in heat is actually a show of respect. Other than that, Chiharu was busy protecting Ikumi from people who might try to claim him. Yes, he's 15. Yes he wants to get Ikumi pregnant. And? His character is a top student. He's not stupid. He's always been careful to not get Ikumi pregnant, however he also wants to make sure that Ikumi's feeling good when they have sex. So that only means that he's an attentive partner. He's gone so far as to apply for the student council so Ikumi can have a safe place to relieve his heat. He's gentle with Ikumi because he knows Ikumi is insecure about being a pregman who doesn't look girly. He is sticking by Ikumi's side even though he knows his mother doesn't like pregmen.

Ikumi is a tsundere. He's a character that tries to deny his desires to the one person who knows him. The reason why he keeps Chiharu at arms length is because he's insecure. He doesn't feel it would look right if Chiharu wasn't with someone who was cute or a girl. Ikumi is prideful, so there is no way he would accept Chiharu's proposal to go on a date. That's not going to happen until he drops the act and give romance a shot. And since a "rival" has appeared, Ikumi has to get off his high horse and finally decide.

Ok so we agree Ikumi has insecurity issues and that he has been victimized but I have to say Chiharu's professed love is just lip service, he actions are all about lust not love. He isn't protecting Chiharu from others, he is staking his claim. He also has a thing for humiliation play during foreplay and sex that disgusts me to no end. Ikumi is not on a high horse, he's seen Chiharu as nothing more than his best friend. Tbh it seems he thinks he is not good enough for Chiharu and that his friend should have a gf. Ikumi sees himself as a freak not just bc he is a pregman but bc he isn't a dainty, pretty pregman. You say he hasn't asked ikumi out on a date bc he thinks he'll say no but that rejection doesn't stop him from asking for unprotected sex and babies all the damn time. He doesn't ask bc he does not really want to date Ikumi, he wants to screw him.

I guess another thing we can agree on is that you can't stand Chiharu while you feel sorry for Ikumi.

I just don't see it that way. I can't victimize Ikumi because I don't see Ikumi as a victim. I see him as a capable character who is able to deal with his own situations. He doesn't want help because he doesn't want his secret to come out, he doesn't want to be judged on it, nor does he want to get others involved with his own problems. Because he's trying to navigate his own life as a pregman, he never thought of romance. It just hasn't come up, regardless of having to deal with his heats. It causes him to have a tsundere attitude when faced with Chiharu's advances; where he can't fully understand his own lustful feelings towards how Chiharu makes him feel, compared to what others might try to do.

The problem I noticed with Ikumi is that he's so set in his ways, that he doesn't realize that others see it as a waste for he and Chiharu to be with each other, even though Chiharu takes care of Ikumi's heat and they're always together; even though Chiharu is open about his feelings for him. Ikumi is the only one denying the relationship everyone else can see. This is why Leon messed with them both and why Miyuki made his move on Ikumi. It's all because Ikumi's constantly denying it. That's why he ran away at the end of this new chapter. It's because he's faced with a choice to either stop lying or give up completely.
