I don’t know about the rest but I think he didn’t try to take her because he knew she wouldn’t want her child to grow up with a yakuza or because she knew that the seme and uke would take care of her even though they aren’t the real parents. And she probably already guessed that they had feelings for each other or that the uke had one sided feelings for the seme ┑(￣Д ￣)┍
no the last panel of the last chapter implies that sentarou is the father (by saying that ririko could only rely on him for something aka the pregnancy and then by touma saying that he won't tell him that)
Her being able to rely on sentarou for this doesnt really mean that he is the dad though.(And if it was really sentarou, i feel ljke she could have told him before)
BUT i do agree that the seme saying "but i wont tell him that" does seem to imply what you said.
Maybe in the original language version they made it more clear Dx
omg i read it again and i can see why shouji might be the dad...
i really wish they explicitly said it ughh this is gonna bother me
Orrrr maybe Touma is also implying that, because he knows that Sentarou have sympathy and care towards Ririko, and maybe Sentarou might feel guilty or regret that he didn't reach out to her after their break up (remember when he blocked her and quit his part-time job) (just my theory┐(´ー｀)┌)
That's why he said he won't tell him that
Its not explicitly but im pretty sure it was implied that the dad is the yakuza. Rememvmber that before dating the uke, she was sad drunk because the man she loved rejected her even though she had slept with him. (That would be when she got pregnant).
And then we learn it was the yakuza that she loved. And the yakuza wanted to take the child and her not wanting a dna test because none of the 2 were the dad.
But what i find odd is we didnt get a single clue as to when and in what circumstances she actually started dating the yakuza.... and at what point did the yakuza knew he was the dad? And how come he didnt even try to take his child....
