I won't say this novel is well written. It has it own flaw, there some plot hole, ect but the story setting, how author make the mpreg thing make sense. It just pushing something big from that hole pretty weird tho.

As for both character.

MC inner dialog is.... how to say this.... emotional. Like a roller coster. Sometime its too dark and depressive. Huhu. So beware.

Normaly in others novel, seme's is far more superior and outstanding but this one the MC is the seme... super sensitive one, low Self-Esteem, so full of feeling, he cried if it too much. The shou/ ML more 'better' with emotion but who knows this novel is on one side perspective only. It refreshing to read the seme characteristic not that almighty and has paralyzed face all time. He quite possesive, jealous (but everyone like that eh it was human instinct afterall) and he thinks wayyy to much which lead to depressive episode.

As for ML he has his own struggle, his own charateristic. They go a girl in the end in story. Ending a bit rushing to.

There alot I want to write but I'm lazy. So I give 3.5
