Hope

Actually in Eijiro's mind, He still didn't fully believe in Green. Eijiro thought that Green had something to hide from him.

 But Eijiro had no idea what Green was hiding. Eijiro still doesn't know that Green knows Eijiro's intention to snatch Katsuki from Shouki.

 If only Eijiro knew about it, he would be very angry with Green. But it becomes a bit problematic because Green is pregnant with Eijiro's child, Eijiro definitely doesn't want to hurt his child. But the one who will become the target of Eijiro's anger is Green. You can't imagine what Green will experience after she gives birth to Eijiro's child, Eijiro could just kill Green because of his anger towards Green.

 "Did you just go to the pregnancy gym?" asked Eijiro. 

 Green nodded slowly, without stopping to think about the answer he simply gave Eijiro an answer to the question. Green didn't look suspicious, that at least made Eijiro less suspicious of Green.
