https://vndb.org/v23205 After flip-flopping from a lot of different VN's I finally settled on Swallowtail. I didn't expect to be immersed in the story considering it felt very rough, both in writing and system but it was unique enough to stand out for me to gain my interest. There is actually is established relationships between the protag and the heroines, which is interesting, the story starts with you already going out with one of the childhood friends Rie, and shows flashbacks from the past also focused on Yuuna, which I think is the true heroine.
Yuuna was originally Shou's (The main character) girlfriend but she randomly disappeared in the festival which is the main focal point of the mystery of the game I guess. The prologue was hella long though I think I was in 5-10 hours before I saw the opening. Saeko is also one of the Ex's of Shou so you could expect that the MC isn't a donkan or hetare, but he's actually a competent and fairly popular guy, albeit a bit bland himself but it made him stand out in the sea of eroge protagonists who sometimes act like idiots or losers. Shou is actually a charismatic guy which made me like him.
The game alternates 50/50 between the past and the present, which is fairly unique but sometimes presented in the interface badly. This is the kind of game I like which seems down to earth with characters not acting like caricatures. I'll make a review when I'm done with this
