Mã Code Trái Tim Của Thủ Khoa Lý Trong Phim Thắp Sáng Anh, Sưởi Ấm Em

Cơn Mưa Mùa Hạ · 8 Tháng mười một 2022

"Thắp sáng anh, sưởi ấm em" - bộ phim chuyển thể từ tiểu thuyết "Chiếc bật lửa và váy công chúa" đang rất hot dạo gần đây với sự tham gia của hai diễn viên chính là Trần Phi Vũ vai Lý Tuân và Trương Tịnh Nghi vai Chu Vận.

Trong tập 5 của bộ phim có một phân cảnh Lý Tuân vẽ trái tim hồng lấp lánh chuyển động bum bum badabum cho Chu Vận bằng mã code, rồi dụ cô tự giải mã đang khiến dân tình quắn quéo vì sự lãng mạn cộp mác thương hiệu của thủ khoa, học bá IT.

Các bạn có thể tham khảo mã code trái tim mà mình đã làm thành công dưới đây:
