Pawn (2020)

Strong female lead at first refuse the child responsibility but later fell in love with the young souls. Fatherly love kick in, and were rewarded by the family like love

Really similar in feel. In both, a man (who is NOT the girl's biological father) slowly grows fond of the child and becomes a father to her. Both are bittersweet, father-daughter movies.
If you liked one of these, you will like the other.

Both of the little girls get adopted to a single man who has been through hardships. They both have cute girls as casts. If you liked one, you might like the other as well

Same male lead that looks tough outside but has a soft heart for little girl. Heart warming movies. A man sacrify himself to raise and protect the little girl, and that little girl has grown up to be a young woman that take care of her adopted dad.

Heart warming movie. The abundant the weak young girl. Protect the young life. Fight for justice. Give love and be love

-2 male leads end up "adopting" a young girl
Voice of Silence is a lot more poignant and sad. Meanwhile, Pawn had its comedic and happy moments.

Adopted kid / grandkid and love unconditionally both kid & father / grandma. Both of them support to each other.

The man adopted a youngster and become family. Great connection. Generation gap but sweet moment. Both give and take, learn from each other

Same story, different execution and countries of origin, with unique cultural perspectives
Both are heartwarming

Both movie involve adult that adopted a young child that is not their biological and fell in love with the young soul. Very touching heartwarming movie

Gives off a similar vibe also has a similar theme of the girl grown up and looking back at her past in a way.

Main lady is a temporary teacher who wasn’t interested in having kids before. She realises a student is being neglected at home and plots to kidnap her and raise her herself.
