Well .. it is always a matter of taste:
You either exert agency in giving the MC you control her/his best shot,
in which case, having your own MC lose to give your other MC the jerk rebound option,
does not sound actually very sound to me, exactly because all Lena is doing all the time
is fending off everyone throwing themselves at her ... so to have her go home with the bully,
seems like giving up .. or seymour or any other ex who demeans her in front of others and
then have the gaull to expect her to yeald.
I mean it always depends on if you or he actually insert yourself and your mindset into the story or just play with the dolls given to you and watch the story play out in different scenarios that are in your mind with the tools that creator provided.
When i discovered these games in 2017 i was more like okay i will insert myself there but since then i don't give a fuck and personally enjoy a lot more games and how Devs decided to present them to me.
I actually find it hilarious when there are some people on this forum that have mental breakdowns because they self insert a tad too much.
To each their own, of course. Just do yourself the favor of going the pleasure route 1st.
