@VawX Just to answer your question, yes. "Loli" doesn't have an age. While it typically refers to younger characters, it can refer to anyone who happens to look young. Shinobu from the Monogatari series for instance.
looking at raws tags that are missing and reasons why
Shoujo Ai there is a yuri sub plot one of the female student fell in love with the FMC tried to stop the progress of FMC and MC bla bla bla she also has a female friend who also like her female friend got rejected but stayed friends she also got rejected by FMC later on
Shounen Ai & crossdressing there is a yaoi sub plot his arc is short but unlike the Yuri sub plot at least dude get to kiss the MC that kiss help the progress of the FMC and MC relationship cause she became really jealous
the ending has a pseudo proposal which is really sweet
