Ohhh.. No worries, that this game needs at least 4GB to run properly, mean that you can sell your phone to buy at least, has 10GB or higher.. Which most likely to play Ecchi game may needs extra cores & Ram to run.. Than on Pc that already more powerful that any higher end phone..🤣
Or look at the requirements that you barely can play it.. Or you can play the Web mode that may used less ram, & may lost the safe data..😅
