Honestly I played this game last 2 year.. and now other visual novel games not entertaining for me .. all time favourite game eternum
Try My Bully is My Lover. It has a reference to Eternum and is overall a good game. Do remember to play Sicae before it tho. The stories are connected.
already done, my bully is my lover, and once in a lifetime
Then go for Companion of Darkness by Berkili4. It's my favourite after Eternum. And if you haven't played Sicae do so too.
Thank you!
being a dik is the best one i came across its on steam trying other games while i wait for season 3
