I love the development. Always had faith he'll change. Euihyun was pretty serious with his decision too, and even if it's a little comical how they made it seem, it's still ultimately Euihyun's choice to pursue Taeju back. Miscarriage out of all things is a really big shock. But I think Euihyun would have preferred if Taeju loved him for him, and not just for responsibility. Taeju does all of these unnecessary things just to keep Euihyun from hating him, but if Euihyun literally says he could go through twice the pain with what Taeju gave him monetary-wise, then that just shows what Euihyun feels about his situation. For someone who has never been in love before, Taeju's pretty extreme and rough with his affection, but is gentle when he comes to realize his love. I think it's a breather to see the author put emphasis on personal reflection and journey, as well as communication and forgiveness in a situation where sitting down and talking it out is hard to come by.
In any case, my wish is for Euihyun and Taeju to talk it out properly without blaming themselves too much. I'd rather have a child be born out of love, not out of guilt of responsibility. And for Euiyoung to grow up well and play with Taeju often.
